Abstract
The utility model discloses a kind of bioconversion medium DNA double helical structure model, belong to teaching aid field.Described bioconversion medium DNA double helical structure model comprises hard plastic square frame, the thin wire be connected with described hard plastic square frame, the plastics ball sheet be connected with described thin wire, the pentagon plastic sheet be connected with described plastics ball sheet, the rectangular plastic tablet that is connected with described pentagon plastic sheet.The utility model is when bioconversion medium, and the observation DNA double helical structure model that student can be intuitively careful, deepens the understanding to DNA double helical structure and study, improve the learning efficiency of student.
Description
(1) technical field
The utility model relates to teaching aid field, particularly a kind of bioconversion medium DNA double helical structure model.
(2) background technology
At present, when learning DNA structure in bioconversion medium, student only watches the picture on teaching material, not easily produces stronger understanding to DNA structure, is not easy to the study of student.
(3) summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind ofly deepens understanding to DNA double helical structure and study, improves a kind of bioconversion medium DNA double helical structure model of the learning efficiency of student.Described technical scheme is as follows:
The utility model embodiment provides a kind of bioconversion medium DNA double helical structure model, described a kind of bioconversion medium DNA double helical structure model comprises hard plastic square frame, the thin wire be connected with described hard plastic square frame, the plastics ball sheet be connected with described thin wire, the pentagon plastic sheet be connected with described plastics ball sheet, the rectangular plastic tablet that is connected with described pentagon plastic sheet, plastics ball sheet represents phosphoric acid, described pentagon plastic sheet represents ribodesose, and described rectangular plastic tablet represents base.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
When bioconversion medium, the observation DNA double helical structure model that student can be intuitively careful, deepens the understanding to DNA double helical structure and study, improves the learning efficiency of student.
(4) accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of bioconversion medium DNA double helical structure model that the utility model embodiment four provides;
Fig. 2 is the exploded view of a kind of bioconversion medium DNA double helical structure model that the utility model embodiment provides.
(5) embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
The utility model embodiment provides a kind of bioconversion medium DNA double helical structure model, see Fig. 1, described a kind of bioconversion medium DNA double helical structure model comprises hard plastic square frame 1, the thin wire 2 be connected with hard plastic square frame 1, the plastics ball sheet 3 be connected with thin wire 2, the pentagon plastic sheet 4 be connected with plastics ball sheet 3, the rectangular plastic tablet 5 that is connected with pentagon plastic sheet 4, plastics ball sheet 3 represents phosphoric acid, pentagon plastic sheet 4 represents ribodesose, and rectangular plastic tablet 5 represents base.A thin wire on each bolt in two ends of hard plastic square frame side, is connected with pentagon plastic sheet with a rectangular plastic tablet respectively by a plastics ball sheet; Use the same method and make one by one containing the Deoxynucleotide model without base; The Deoxynucleotide model several made, is through on thin wire successively according to certain base sequence, forms a DNA chain; Make another DNA chain in the same way, and be connected to each other; Stretching double-strand rotates, and namely obtains an a kind of bioconversion medium DNA double helical structure model.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
When bioconversion medium, the observation DNA double helical structure model that student can be intuitively careful, deepens the understanding to DNA double helical structure and study, improves the learning efficiency of student.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
