Abstract

The utility model relates to a dynamic teaching aid. The dynamic teaching aid is characterized in that the dynamic teaching aid is composed of a panel, codons, A and P site binding site points, a directional line representing mRNA, hooks representing tRNA and circular marks representing aminoacyl; a wooden blackboard is adopted to make the panel; the codons arranged on the panel are 1cm-height vertical lines which are arranged equidistantly; two sides of the codons are provided with the directional line representing mRNA which intersects with the codons; the A and P site binding site points are arranged below the codons; the hooks representing tRNA are arranged below the codons; three strands of metal wires are stranded so as to form each hook, and one end of the hook is spared to form three hook-shaped metal wire ends which are connected with the codons, and the other end of each hook is twisted so as to form a hook-shaped strand which is connected with one circular mark representing aminoacyl; and the circular marks representing aminoacyl are circular marks. The dynamic teaching aid of the utility model is advantageous in simplicity, intuitiveness and practicality; with the dynamic teaching aid adopted to give lessons, the students can intuitively grasp teaching contents, and teachers can arrange the teaching contents more reasonably, thereby improving teaching quality.

Description

A kind of dynamic teaching aid

Technical field

The utility model belongs to a kind of teaching aid of the biosynthetic process for " biological chemistry " study course professor protein, particularly a kind of dynamic teaching aid.

Background technology

At present, domestic in secondary vocational school's " biological chemistry " study course, the teaching of protein biosynthetic process is very abstract, a complicated process.The teacher demonstrates without any teaching aid when lecturing this part course, is to be described or to lecture in the mode of explanation limit, blackboard top picture by language, and exist: 1, draw in the classroom wastes instructional blocks of time; 2, adopt the form any confusion of wall chart, the problem such as directly perceived, difficult grasp, thereby can affect classroom instruction and quality of instruction.

Summary of the invention

The utility model has overcome the defective of above-mentioned existence, and purpose is for solving the teaching of the professor of secondary vocational school's " biological chemistry " protein biosynthetic process, improve the quality of teaching, a kind of dynamic teaching aid being provided.

The dynamic teaching aid content Description of the utility model:

The dynamic teaching aid of the utility model, it is characterized in that: be by the plate face, codon, A, P position binding site, expression mRNA direction line, the circle of the hook of expression tRNA and expression aminoacyl indicates and forms, the plate face adopts wooden blackboard to make, be provided with codon at the plate face, codon is the high vertical bar of equidistant 1cm, per 3 is one group, below codon, be provided with A, P position binding site, be provided with expression mRNA direction line in the transverse center position of codon, expression mRNA direction line and codon cross, the left end of expression mRNA direction line is 5 ', right-hand member is 3 ', below codon, be provided with the hook of expression tRNA, the hook of expression tRNA adopts 3 strands of tinsels to be crafted into, wherein an end is reserved 3 tinsel heads and is hook-shaped and links to each other with codon, the other end twists into one and is hook-shaped circle with the expression aminoacyl and indicates and to be connected, the circle of expression aminoacyl is denoted as circular the sign, top is with coupling hook, the bottom is provided with abutment ring, and mark has " egg " in circular the sign, " paddy ", or " Soviet Union " word.

The dynamic teaching aid of the utility model has simple, directly perceived, practical characteristics, adopt dynamic teaching aid dynamic and static the combining of giving lessons, can attract student's learning interest, make the student can grasp intuitively the content of courses, the teacher can more rational Teaching content, improves the quality of teaching.

Description of drawings

Fig. 1 is dynamic teaching aid structure synoptic diagram

Among the figure: the 1st, plate face, the 2nd, codon, the 3rd, A, P position binding site, the 4th, expression mRNA direction line, the 5th, the hook, the 6th of expression tRNA, the circle of expression aminoacyl indicates.

Embodiment

The dynamic teaching aid of the utility model is to realize like this, specify below in conjunction with accompanying drawing, see Fig. 1, the dynamic teaching aid of the utility model, by plate face 1, codon 2, A, P position binding site 3, expression mRNA direction line 4, the circle of the hook 5 of expression tRNA and expression aminoacyl indicates 6 and forms, plate face 1 adopts wooden blackboard to make, be provided with codon 2 at plate face 1, codon 2 is the high vertical bars of equidistant 1cm, per 3 is one group, below codon 2, be provided with A, P position binding site 3, be provided with expression mRNA direction line 4 in the transverse center position of codon 2, expression mRNA direction line 4 crosses with codon 2, the left end of expression mRNA direction line 4 is 5 ', right-hand member is 3 ', below codon 2, be provided with the hook 5 of expression tRNA, the hook 5 of expression tRNA is to adopt 3 strands of tinsels to be crafted into, wherein an end is reserved 3 tinsel heads and is hook-shaped, link to each other with codon 2, the other end twists into one and is hook-shaped, indicates 6 with the circle of expression aminoacyl and is connected, it is circular the sign that the circle of expression aminoacyl indicates 6, top is with coupling hook, and the bottom is provided with abutment ring, and mark has " egg " in circular the sign, " paddy ", or " Soviet Union " word.

The dynamically making of teaching aid:

Adopt wooden blackboard manufactured Board face 1, drawing at plate face 1 is the high vertical bar of equidistant 1cm, and per 3 are one group and represent several codons 2 that the A position that arranges and P position binding site 3 are inferior interior 2 binding sites of little base below codon 2.Be provided with expression mRNA direction line 4 at the two ends of codon 2 and cross with codon 2, expression mRNA direction line 4 adopts diameters greater than 2mm, and the tinsel of long 75cm is horizontal, and the left end that represents mRNA direction line 4 is 5 ', right-hand member is 3 ', in order to the direction of mark mRNA.Below codon 2, be provided with the hook 5 of expression tRNA, the hook 5 of expression tRNA is to adopt 3 strands of tinsels to be crafted into, wherein an end is reserved 3 tinsel heads and is hook-shaped, representing anticodon links to each other with codon 2, the other end twists into one and is hook-shaped circle with the expression aminoacyl and indicates 6 and be connected, it is circular the sign that the circle of expression aminoacyl indicates 6, represent aminoacyl-tRNA, the circle of expression aminoacyl indicates 6 top with coupling hook, the bottom is provided with abutment ring, and mark has " egg ", " paddy " or " Soviet Union " word in circular the sign.

When giving lessons: can finish by dynamic demonstration the teaching of professor's protein biosynthetic process, have simple, directly perceived, practical characteristics, adopt the dynamic and static mode that combines to impart knowledge to students, lively attraction student's learning interest, make the student can grasp intuitively the content of courses, the teacher can more rational Teaching content, improves the quality of teaching.
