The present invention relates to a DNA double helix structure assembly mechanism. More specifically, the present invention relates to a DNA double-helical model assembly mechanism that can be easily disassembled and assembled by its shape and has a form similar to the actual DNA structure, which can enhance the viewer's understanding and increase the learning effect.

Biotechnology, BT (BioTechnology) is one of the technological fields that are in the spotlight with the development of various advanced technologies in modern times. The BT industry is expanding not only various medical and pharmaceutical fields but also new materials and environmental technologies using biotechnology, and various industrially applicable technologies are being developed. As a result, the public's interest in biotechnology is gradually increasing, and in connection with this, learning related to biotechnology is being actively conducted by elementary, middle and high school students.

However, the DNA double helix structure, which is essential for basic learning of biotechnology, is very complicated in three dimensions, making it easy for elementary, middle, and high school students to understand easily by the pictorials presented at ordinary education sites. It is difficult. In order to make up for such drawbacks, companies such as textbook suppliers have produced and supplied models of three-dimensional DNA double-helical structures in three dimensions, but most of them are in one-piece form, and the purpose of making them assembled for learning is the case. It is not intended to be assembling to reduce the volume of shipping or storage. In addition, the above models are especially intended for exhibition purposes, so they are made of high-quality materials and structures that are sturdy and easy to exhibit and view so as not to be damaged easily. Therefore, the price is inevitably set so that it is difficult for ordinary students to bear, and it is very difficult for ordinary students to own such a model individually. However, the most effective means of recognizing and understanding such complex three-dimensional shapes for elementary, middle, and high school students is to make them by themselves. The demand has been raised steadily.

In order to solve such a requirement, Korean Patent Registration No. 20-0234659 (DNA double-helix assembly member) has disclosed a member capable of assembling a DNA double helix structure with a simple structure. The assembly member is composed of a base plate and a support shaft for supporting the entire model, a rectangular plate-shaped base plate having assembly protrusions at both ends in the longitudinal direction, and a backbone band having assembly holes coupled to the assembly protrusions of the base plate at regular intervals. 1, a double helix model made by combining the assembly member is shown. As shown in FIG. 1, a support shaft 112 is vertically provided at the center of the base plate 111, and a shaft hole 121b is formed at the center of each base plate 121 to support the support shaft 112. It is sandwiched at regular intervals. Assembly bases 121a are formed at both ends of the base plate 121 in the longitudinal direction, and the assembly protrusions are coupled to the assembly holes 122a formed at regular intervals in the backbone strip 122 to form a double spiral structure. You can do it. The base plate 121 and the backbone strip 122 may be made of a resin material or a paper material, thereby reducing the weight of the product itself so that young students can handle it safely and at the same time reduce the price of the product. have.

However, the conventional double spiral model 100 shown in FIG. 1 has the following problems. First, the base plates 121 are inserted into the support shaft 112 by the shaft hole 121b formed at the center thereof, and are spaced apart from each other at regular intervals. The base plates 121 are substantially separated by the user. There is no choice but to adjust it, so it is impossible to maintain a precisely constant interval. In addition, even if the interval is constant to some extent, the intervals are different for each user, so each person who makes a model has a different shape. Second, unlike the typical DNA pictorial, it may cause confusion. When the assembling protrusion 121a of the base plate 121 is fitted into the assembling hole 122a of the backbone strip 122 to form the coupling and the overall shape of each other, the assembling protrusion is substantially out of the outer wall surface of the backbone strip 122. It is inevitable that the tip of 121a) protrudes, and the assembling protrusion 121a is seen to rise innumerably above the backbone 122 as shown in FIG. There is no such projection. In adults, the ability to find the association and correspondence between the complex original shape and the symbolized shape and the spatial perception ability to recognize the three-dimensional shape are sufficiently developed. You can think of the shape. However, at the age of elementary school students whose primary use of the above cited subjects is a period when such abilities are not fully developed, an inaccurate model does not help understanding the original shape but rather adds confusion. It is very likely. Third, the DNA structure can be simulated to some extent after completion, but it is difficult to realize the actual DNA structure at the assembly stage, and thus no educational effect can be expected at all. The process of producing the actual DNA depicted in conventional pictorials is difficult to implement with the model cited above. In particular, in order to simulate the actual process similarly, the middle portion of the base plate 121 must be separated into two, and the base plate 121 in the above-mentioned quotation is integral and the central portion in the shaft hole (121b) Since it is fitted to the support shaft 112, it is completely different from the actual shape. Likewise, the backbone 122 has a long strip shape until the model is completed, and the remaining parts that are not assembled during the assembly process are stretched out, which is not seen in the actual DNA formation process. In this way, the actual and the models are completely different forms, which may cause confusion and misunderstandings to learners in terms of educational effect.

In addition, the Korean Utility Model Registration No. 20-0414747 (DNA double helix structure model assembly mechanism) filed by the present applicant has provided a DNA double helix structure model that eliminates the above problems, the design of the DNA structure Since the form is faithfully copied, the educational effect is high, but in detail, there is a different part from the actual DNA structure, which is suitable for the elementary and intermediate education, but it is insufficient in the advanced education.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to provide a DNA double helix structure model assembly mechanism that faithfully simulates the actual DNA structure. More specifically, by faithfully replicating the actual DNA as well as the actual form of each unit, the understanding and education can be enhanced not only in the finished product but also in the assembly process, and as a result, it is used as an advanced educational material. It is to provide a possible DNA double helix structure assembly mechanism. In addition, the object of the present invention is to provide a DNA double helix structure model assembly mechanism to enhance the aesthetics to achieve aesthetic effect as well as educational effect when displaying the finished product.

DNA double helix structure model assembly of the present invention for achieving the object as described above, has a body of a first predetermined length, the first chain assembly at one end of the body to be assembled with other chain units And a plurality of chain units each having a second chain assembly formed at the other end and having a first coupler formed at the center of the body so as to be combined with the following base units ; A plurality of base units having a body having a second predetermined length and having second coupling holes formed at both ends of the body so as to be coupled to the first coupling holes of the chain unit ; Characterized in that comprises a. At this time, the first coupler and the second coupler is characterized in that formed in the pair of the coupling protrusion and the coupling hole. In this case, the coupling hole may penetrate the body in which the coupling hole is formed, and the coupling hole and the coupling protrusion may not have the same cross-sectional shape.

In another aspect, the present invention, the first chain assembly and the second chain assembly are any one selected from the form of a pair of chain assembly protrusion and chain assembly, tooth form that can be disassembled and assembled with each other, screw assembly form, auxiliary chain assembly is further added. Characterized in that it is formed in one form. At this time, in the double helix formed by assembling a plurality of the chain unit and the base unit, the chain assembly is predetermined after assembly so that the height of the double helix can be varied by extending or contracting both sides of the double helix. It may be formed so as to enable rotation within the range.

Alternatively, the chain unit may further include a first chain angle adjusting tool formed in the first chain assembly, such that the chain units are coupled to each other to form a spiral shape at a predetermined angle, and the second chain assembly includes a first chain angle adjusting tool . It is characterized in that the two-chain angle control is further formed.

When the chain assembly is in the form of a pair of chain assembly holes and chain assembly protrusions, the chain angle adjusting tool further protrudes from one chain assembly end and is further recessed from the angle adjusting protrusion and the other chain assembly end having a directional shape. And a pair of angle adjusting holes having a cross section having the same shape as that of the cross section of the angle adjusting protrusion. When the chain assembly is a screw assembly type, the chain angle adjusting tool is a screw thread to rotate the screw only to a predetermined angle. It is preferable that it is formed in the shape which prevents extension.

In addition, when the chain assembly is a form in which the auxiliary chain assembly is further added, the chain unit is assembled by combining the auxiliary chain assembly and the chain assembly, the auxiliary chain assembly is made of an injection molding or rubber ring It is characterized by. In addition, the body of the chain unit is preferably formed to have a constant radius of curvature.

In addition, the base unit is a base assembly is formed in the middle of the body so that it can be disassembled and assembled into two parts, the base assembly is formed in the form of a pair of base assembly and base assembly hole or tooth form that can be disassembled and assembled with each other It is done. In this case, the base assembly is characterized in that one, two or four, and the base assembly is formed so that the length of the two parts of the base unit separated by the base assembly is different from each other It features.

In addition, the chain assembly or base assembly is characterized in that it further comprises a magnetic material to enhance the binding force.

In addition, the present invention is a support for supporting the spiral axis direction of the double helix formed by assembling and combining a plurality of the chain units and a plurality of the base units; A pedestal for supporting the double helix by standing up the support in the center; Characterized in that further comprises. At this time, the support and the pedestal are provided on each of the upper and lower sides in the spiral axial direction of the double helix, at least one support rod for supporting each other provided on the upper and lower sides; It is preferred to further comprise. The upper or lower support is further characterized in that the motor is further provided so that the double helix can rotate, and the pedestal, the support rod or the support is further provided with a light source for illuminating the double helix at a predetermined position. It is preferable that it is done. In addition, the base unit and the chain unit, characterized in that each has a distinctive color or transparency to enable classification. In addition, the base unit and the chain unit is preferably determined in shape so that the double helix forms one wheel per 10 base units, and the base unit and the chain unit is the diameter of the double helix versus the double helix It is preferable that the shape is determined so that the ratio of the height of the wheels is 1.5 or more and 2 or less.

Hereinafter, with reference to the accompanying drawings the DNA double helix structure model assembly mechanism according to the present invention having the configuration as described above will be described in detail.

2 simply shows the actual DNA structure. In short, DNA is a polymer organic material in which a plurality of unit substances called nucleotides are connected to each other. As shown in FIG. 2 (A), DNA is a twisted ladder to form a double helix structure. A, T, C, and G each represent four bases, S represents deoxyribose, and P represents phosphoric acid. When the double helix is unfolded, it becomes a ladder form as shown in FIGS. 2 (B) and 2 (C). Usually, the diameter of the helix is 2 nm, the vertical length of one helix is 3.4 nm, and 10 nucleotides will form a helix. Figure 2 (B) shows the unfolded half of the DNA helix including a simple chemical structural formula, Figure 2 (C) is to simplify the emphasis on the binding form. Deoxyribose and phosphoric acid are alternately bonded to each other (...- PSPSP -...) to form a long string form, and one base is bound to each deoxyribose. The bases of the two strings thus formed are bonded to each other, resulting in a DNA like a ladder with two legs consisting of scaffolds consisting of two bases linked together and alternating deoxyribose-phosphate. The shape is twisted to form a double helix structure. The base constituting DNA is adenine (A), guanine (G), cytosine (C), thymine (T), and adenine (A) is thymine (T) and guanine (A). G) has a property of binding only to cytosine (C). As shown in FIG. 2 (B), A and T are bonded at two places, and C and G are bonded at a weak hydrogen bond.

When the DNA of such a type is produced as an educational model, the intermediate and intermediate textbooks have a finished product in the form of a double helix, and a level capable of decomposing the double helix chains and bases is sufficient. However, when used as a high-quality teaching material, it can be expected that the higher the educational effect is equipped with all the features of the actual DNA structure represented in FIG.

Figure 3 is a perspective view of the DNA double helix structure model assembly according to the present invention. DNA double helix structure model assembly 200 according to the present invention supports a plurality of base units 210 and a plurality of chain units 220 forming a double helix, and the double helix to be stably displayed The pedestal 230, the support 231, the support rod 232 is made up. The base unit 210 has a body of a predetermined length as shown in Figure 3, the chain unit 220 has a body of a predetermined length independent of the base unit 210. (The combination of the base unit 210 and the chain unit 220 will be described in the description of FIGS. 5, 6, and 7 below.) The chain unit 220 is a torus having a curvature. It is preferable to have a body which is formed in equal form at regular intervals.

4 is a top view of the DNA double helix structure model assembling apparatus 200 according to the present invention when viewed from above, and having a torus-like body as described above, as shown in FIG. When the unit 220 is connected, the circular shape is formed by the curvature radius of the body of the chain unit 220 when viewed from above, and when the body of the chain unit 220 does not have the radius of curvature, the smooth circular shape is seen when viewed from above. Instead of forming a polygon shape. In order to simulate the actual DNA form more closely, it is preferable to have a radius of curvature as described above. However, the chain unit 220 may not have a radius of curvature for ease of fabrication. In addition, although the cross section of each base unit 210 and the chain unit 220 in the drawings of the present specification is shown to take a circular pipe shape, for ease of manufacture to take a pipe shape of a polygonal cross section It is okay. In particular, the base unit 210 may be formed in a flat form so that the separation of the separation portion is easier. In any case, the base unit 210 and the chain unit 220 is preferably manufactured by an injection process as a plastic material. In addition, the base unit 210 and the chain unit 220 is preferably manufactured by different colors so as not only to classify each unit to the user to distinguish from each other, but also to satisfy the aesthetic satisfaction. That is, the chain unit 220 and the base unit 210 to have a different color, or the base unit 210 itself to have up to four (the actual DNA base type or the number of base pairs that can be combined), or some units The silver may be manufactured by various methods such as making it transparent.

5 is a front view of the DNA double helix structure model assembling apparatus 200 according to the present invention, and FIG. 6 is a front view when a part of the DNA double helix structure model assembling apparatus 200 according to the present invention is disassembled. . And Figure 7 is an exploded view illustrating in more detail the assembled state of the chain unit 220 and base unit 210.

The base unit 210 and the chain unit 220 are bonded to each other to form a double helix, the chain units 220 are connected to each other to form a double helix, the base unit 210 is bonded between the chain unit 220 The two helices are firmly joined together, forming a bridge. DNA double helix structure model assembly 200 according to the present invention has the purpose of use as a textbook that can easily understand and learn the complex structure of the DNA, in order to more closely mimic the DNA structure as described above The scaffold portion formed by the binding of the bases is represented by the base unit 210, and the bridge part composed of alternating bonds of deoxyribose-phosphate is represented by the chain unit 220.

Base unit 210 serves to bind the two helices as shown in Figure 5, in order to perform this function, the base unit 210 is a separate body that can be separated as a coupling protrusion (both ends) 211 is formed, and each coupling protrusion 211 is inserted into and coupled to the coupling hole 221 formed at the center of the chain unit 220. Of course, at this time, the binding unit in place of the binding protrusion in the position of the binding protrusion 211 of the base unit 210, and also in the coupling hole 221 position of the chain unit 220 by forming a binding protrusion instead of the base unit the base unit 210 and the chain unit 220 may be combined. In this figure, the coupling protrusion 211 is formed at both ends of the base unit 210, and the coupling hole 221 is formed in the middle of the body of the chain unit 220. In addition, in the drawing, when the base unit 210 and the chain unit 220 are combined, the coupling hole 221 is formed to penetrate the body of the chain unit 220, so that the coupling protrusion 211. Although the end of is to be exposed to the outside, of course, the coupling hole 221 is formed so as not to penetrate the chain unit 220, the end of the coupling protrusion 211 may be exposed to the outside. In addition, although the cross-sectional shape of the coupling protrusion 211 and the coupling hole 221 is circular in this drawing, the cross section may be any shape such as a triangle, a square, an ellipse, a cross, a star shape and not a circular shape. In addition, the cross-sectional shape of the coupling protrusion 211 and the coupling hole 221 is the same in this drawing so that the coupling protrusion 211 can be tightly fitted to the coupling hole 221, but at this time to facilitate assembly The cross-sections of the coupling protrusion 211 and the coupling hole 221 may be different in shape so as to reduce the frictional force of the contact portion when the fitting. For example, the coupling hole 221 may have a circular cross section, and the coupling protrusion 211 may have a cross section. As such, when the cross-sectional shapes of the coupling protrusion 211 and the coupling hole 221 are different, the cross-sectional shape of the coupling protrusion 211 is different according to the type of the base unit 210 to distinguish the base unit 210. You can do it easily.

As described above, the base unit 210 is a component that simulates a scaffold, that is, one base bond pair, and in fact, one base bond pair is formed by combining two bases, so that the base unit more closely simulates the base. 6 and 7, the base assembly 212 is formed in the middle of the body, so that the unit 210 can be separated into two. In the embodiment depicted in Figures 6 and 7, the base assembly 212 is in the form of a tooth so that it can be firmly coupled to each other. Of course, in addition to the teeth form as shown, it is made of a pair of insertion protrusion-insertion hole, such as the disassembly and assembly portion of the chain unit 220, or provided with a magnet at each separation end to be disassembled and assembled with each other, etc. If it satisfies the purpose of disassembling and assembling into two parts from the middle of the body of the base unit 210 may be formed in any form.

In this case, the base assembly 212 is only one kind, so that all of the decomposed base units 210 may be simply configured to be assembled with each other. In order to more clearly express only binding between T (thymine) / G (guanine) -C (cytosine), two or four types of base assembly 212 may be used. In the case of four types of the base assembly 212, A and T can be formed by using the property that only A (adenine) -T (thymine) / G (guanine) -C (cytosine) can be bonded to each other. For example, A can be combined with each other by having a round insertion protrusion, and T with a round insertion hole, so that they can be shaped differently, and G and C are also the same (for example, G is a triangle insertion hole and T is a triangle insertion hole). By providing a) to be distinguished from the A and T. When the base assembly 212 has two forms, it is divided into two groups A, G / T, and C (for example, A and G / T and C are provided with insertion protrusions and insertion holes, respectively). To form a form that can be combined.

That is, when the base assembly 212 has one form, all (decomposed) base units 210 can bind to each other, so that the structure of the DNA is close to itself, but only specific bases are combined. It may not be enough. In the case of two types of base assembly 212, at least A and G cannot bind to each other, and T and C cannot bind to each other (in this case, not only the assembly of AT / GC but also the assembly of AC / GT) Can be generated) but it can more closely simulate the actual base bond pairs. When the base assembly 212 has four forms, it is possible to perfectly simulate the actual DNA structure, and the learning effect can also be maximized. On the other hand, as the type of base assembly 212 is reduced, the production is easier, and the manufacturing cost can also be considered to be reduced. Therefore, the type of the base assembly 212 may be any one, two or four.

In addition, although the base assembly 212 is shown to be provided at the center of the base unit 210 in FIG. 3 or less, as shown in FIG. 2, A and G have a larger molecular structure than T and C. Since the base assembly 212 is formed to be deflected instead of the center of the base unit 210, two parts of the base unit 210 separated by the base assembly 212 are mutually different. It may be formed to have a different length. In particular, as shown in Figure 8, it is preferable that the shape of the bonded portion is changed when the base assembly 212 is bonded. To this end, the base unit 210 has to be designed differently according to the shape of the base unit. As shown in FIG. 8, the coupling portion of the base assembly 212 has a square tooth / wave when the base unit 210 has a circular pipe shape. Teeth (Fig. 8 (A)), triangular / semicircular for each face in the form of square pipes (Fig. 8 (B)), triangular / semicircular in wide view in the flat form (Fig. 8 (C)) This can be done as such. Of course, FIG. 8 is merely an example, and a coupling portion of the base assembly 212 may be formed in any form within a range not departing from the spirit of the present invention.

Combining the features of the present invention as described above, A, T, C, G can be expressed in various ways. For example, the base assembly 212 has one form, but the base unit 210 representing the AT base pair is red / the base unit 210 representing the CG base pair is blue, and the base assembly 212 ) So that the base unit 210 can be separated into the long and short side by biasing, the red and long base unit part is A / the red and short base unit part is T / blue and the long base unit part is G / blue and short base part Part of the unit will be able to represent C. Alternatively, the base assembly 212 has four forms, and the color of a part of the base unit corresponding to A, T, C, and G is red, yellow, blue, and white, respectively, and the base assembly 212 is also used. ), The base unit with red, long, triangular insertion protrusions is A / yellow, short, and the base unit with triangular insertion hole is T / blue, long, and base portion with round insertion protrusions is G / white, short. And a portion of the base unit with a round insertion hole may indicate C. In the above two examples, the four bases can be completely distinguished and expressed, but in the case of the former, many similar parts can be used, and the educational effect may be slightly reduced, but in the latter case, the production process is complicated and the production is made. Rather than being able to increase costs, the reproducibility of the actual DNA structure is very high, providing an educational effect.

As shown in FIGS. 5, 6, and 7, the chain unit 220 has a coupling hole 221 formed in the middle of the body, and the coupling protrusion 211 formed at both ends of the base unit 210. ) Can be combined. (Also, as described above, the coupling protrusion-coupling holes may be provided opposite to each other.) Chain assembly holes 222a and chain assembly protrusions 222b are formed at both ends of the chain unit 220, respectively. The other chain unit chain assembly protrusion 222b is inserted into the chain unit chain assembly hole 222a of the assembly. Of course, the chain assembly portion consisting of a pair of the chain assembly hole (222a) -chain assembly protrusion (222b), as shown in Figure 6 and 7 base assembly 212 as shown in the tooth form can be assembled It's okay. In addition, the chain assembly portion may be made of a screw shape, as shown in Figure 9 is further provided with an auxiliary chain assembly 224, chain assembly formed on both ends of the chain unit 220 By being coupled to the auxiliary chain assembly 224 may be assembled to each other. At this time, the auxiliary chain assembly 224 may be formed of an injection molding or a rubber ring. In particular, when the auxiliary chain assembly 224 is further provided as shown in FIG. 2, as shown in FIG. 2, the chain is formed of phosphoric acid (P) -deoxyribose (S), and the auxiliary chain assembly ( 224 represents the phosphoric acid (P) and the chain unit 220 to represent the deoxyribose (S) to more closely mimic the actual, it is possible to increase not only the ease of assembly but also the educational effect at the same time.

In the embodiment shown in the figure used as a chain assembly hole of the chain assembly hole (222a)-chain assembly protrusion 222b, but as described above, in addition to the pair of the chain assembly-chain assembly protrusion teeth, screw assembly Any form of assembly may be used without departing from the spirit of the present invention, such as a shape, a shape using an auxiliary chain assembly, and the like. In addition, like the base assembly, the magnetic body may be provided at an appropriate position of the chain assembly so that the chain units 220 may be more strongly coupled by magnetic force.

At this time, when the chain assembly holes 222a and the chain assembly protrusion 222b are inserted and coupled to the plurality of chain units 220 only, the assembly portion of the chain unit 220 may rotate. When the chain unit 220 is assembled as described above to be rotatable by a predetermined angle, holding both sides of the double helix made by assembling a plurality of base units 210 and the chain units 220 The height of the entire double helix may be increased or decreased by pulling or pressing.

Of course, the height of the double helix may be varied as described above, but in order to form a spiral form at a suitable interval so that the height of the double helix is fixed without being variable, so that the assembly part is not rotated once assembled. It is preferable to be. Therefore, as shown in FIG. 7, the chain angle adjusting protrusion 223b having a rectangular cross section protruding from the inside of the chain assembly hole 222a and the chain angle adjusting protrusion 223b are inserted from the outside of the chain assembly protrusion 222b. It is provided with a chain angle control hole (223a) formed to have a cross section of the shape having a direction so as to be recessed. (Here, the directional shape is a shape such as a rectangle, ellipse, triangle, etc., which can be inserted only at a certain angle and prevents rotation anymore after being inserted.) Here, the chain assembly hole 222a The chain angle control projection (223b) in the inside, the chain angle adjustment hole (223a) to be formed on the outside of the chain assembly protrusion (222b), of course, the chain angle control hole (223a) is more inside the chain assembly hole (222a) It is formed to be recessed, the chain angle control projection (223b) may be formed to protrude further from the outside of the chain assembly protrusion (222b), in this case, since the body length of the single chain unit 220 may be too long It is preferable to configure as the former. Thus, by providing a chain angle control hole (223a) and a chain angle control projection (223b), not only to ensure that the assembly portion of the plurality of chain unit 220 to form a certain angle, but also to rotate the assembly after the fixed angle It can be kept tight.

When the chain assembly is a pair of chain assembly holes 222a and chain assembly protrusions 222b, the chain angle adjusting tool is preferably in the form of a pair of chain angle adjusting protrusion-chain angle adjusting holes as described above. . In other cases, for example, when the chain assembly is in the form of a screw, the above-described structure cannot be used. In this case, by forming a structure in which the extension of the screw thread is prevented so that the screw rotates only to a predetermined angle. When the chain units 220 are assembled to each other, it is preferable to achieve a predetermined angle with each other when the screws are completely tightened. In addition, in the case of using the auxiliary chain assembly, all forms used in the form of the chain assembly can be used in the form of the chain assembly-irradiated chain assembly, and the chain angle assembly is the chain assembly-irradiated chain assembly It is preferred to be formed at the joining portion.
