Abstract
The utility model discloses a kind of baculoviral model teaching aid of helical symmetry, it is characterized in that: comprise spiral body and be all located at the module of described body outer surface.The utility model structure is simple, well arranged, dismounting is flexible, vivid, production technology is simple, with low cost.
Description
Technical field
The utility model relates to teaching aid field, particularly relates to a kind of baculoviral teaching aid model of helical symmetry.
Background technology
The baculoviral of helical symmetry is one of virus three kinds of grown forms, is also one of virus three kinds of symmetric systems.Viral nucleic acid is crimped onto in the spirality capsid be made up of the protein subunit repeated.Protein subunit centrally axle arranges in the shape of a spiral, the rock-steady structure that height of formation is orderly, symmetrical.The housing of helical symmetry forms direct rod shape, bends the baculovirus particles such as shaft-like.Typical Helical symmetry virus such as TMV is a kind of model plant virus having material impact in virology development history each stage.It is hard shaft-like, and because its nucleic acid has suitable Protein capsid parcel and protection, therefore structure is very stable.
Generally show the structure of helical symmetry baculoviral with schematic diagram at teaching field, but the picture of plane can not analyze its structure well, explains its building-up process, so need a three-dimensional model to carry out auxiliary explanation.
Summary of the invention
The purpose of this utility model is to provide the baculoviral teaching aid model of simple, the vivid helical symmetry of a kind of structure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of baculoviral model teaching aid of helical symmetry, comprise spiral body and be all located at the module of described body outer surface, described module card is located in described body, described module is provided with the groove matched with described body.
In technique scheme, module is shoe tree type, is fastened on body outer surface by groove.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model is reassembling type model teaching aid, and structure is simple, easy to operate, vivid, reduction packaging space, saving transportation cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model splits.
Wherein: 1, body; 2, module; 3, groove.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1-2, a kind of baculoviral model teaching aid of helical symmetry, comprise spiral body 1 and be all located at the module 2 of body 1 outside surface, module 2 is fastened in described body 1, module 2 is provided with the groove 3 matched with body 1.
Module 2 is shoe tree type, is fastened on body 1 outside surface by groove 3.
Module 2 represents the protein subunit of the baculoviral of helical symmetry, body 1 represents viral DNA.
Claims (1)
