Abstract
The utility model relates to a model of a DNA double-spiral structure; the aim is to provide a DNA model with convenient combination, and a plane state can be changed into a stereo state. The model of the DNA double-spiral structure of the utility model is characterized in that the utility model is composed of hard plastic sheets and an iron wire which is provided with circular rings at both ends; the hard plastic sheet can be classified into circular structures, regular pentagon structures and oblong structures which respectively represent phosphoric acid, deoxyribose and base; hooks respectively fixed to both transverse sides of each hard sheet are connected to the circular rings of the iron wire. Circular plastics are longitudinal connected by the iron wire. The model of the DNA double-spiral structure of the utility model with simple structure and low cost can basically show the plane structure of the DNA; when rotated from both ends, the utility model can show the stereo structure of the DNA.
Description
Technical field:
The utility model relates to a kind of teaching mode, particularly a kind of DNA model.
Background technology:
In the biological course in junior middle school, the double-spiral structure of DNA is the basis of disclosing genetic secret, the general structure that adopts the form performance DNA of picture in teaching.
Summary of the invention:
The purpose of a kind of dna double helical structure of the utility model model provides a kind of convenient combination, can be become the DNA model of solid shape by the plane.A kind of dna double helical structure of the utility model model is characterized in that, it is to have the iron wire of annulus to constitute by hard plastic sheet and two, described hard plastic sheet is divided into circle, regular pentagon and rectangle structure, representative respectively, phosphoric acid, ribodesose and base, the rectangular plastic tablet of described representative base scribbles 4 kinds of different colours and represents 4 kinds of different bases), the both lateral sides of described hard plastic sheet is fixed with hook respectively and is connected on the annulus of iron wire.Vertically connect between round plastic with iron wire.A kind of dna double helical structure of the utility model model structure is simple, and cost is low, can show the planar structure of DNA substantially, when rotating from two ends, can also show the spatial structure of DNA.
Description of drawings:
Figure one is a kind of dna double helical structure of the utility model structure of models synoptic diagram.
Embodiment:
Shown in figure one, a kind of dna double helical structure of the utility model model is that the hard plastic sheet by circular 1, regular pentagon 2 and rectangle 3 laterally connects to form a row by hook, iron wire 4, described row moulds between the material structure and is vertically connected by iron wire 5 by circular hard plastic sheet 1, forms strip.Circle of the present utility model, regular pentagon and rectangular plastic tablet are represented phosphoric acid, ribodesose and base respectively, and to the different choice of rectangle plastics color, represent different bases.Can connect two handles, 6,7 convenient rotation dna double helical structure model performance three-dimensional shapes at the two ends of dna double helical structure model.
Claims (2)
1, a kind of dna double helical structure model is characterized in that, it is to have the iron wire of annulus to constitute by hard plastic sheet and two, described hard plastic sheet is divided into circle, regular pentagon and rectangle structure, and the both lateral sides of described hard plastic sheet is fixed with hook respectively and is connected on the annulus of iron wire.Vertically connect between round plastic with iron wire.
2, it is characterized in that according to the described a kind of dna double helical structure model of claim 1, can connect two handles at the two ends of dna double helical structure model.
