Type and tailgate anal spine model.
The head model is hollow wooden icosahedron.
The tail neck model is hollow T-shaped pipe wide at the top and narrow at the bottom.
It is 2 centimetres of small sircle holes that the caudal sheath model has aperture for upper end, and there is the wood of the big hole that aperture is 4 centimetres lower end
Rod.
The tailgate anal spine model is the wooden thing of hexagon stool shape.
The tailfiber model is obtuse angle thicker wire.
The cell model wooden hollow oval ball.
The connecting rod of the connection head model and afterbody model is wooden connecting rod.
The projection is wooden projection.
The nucleic acid model is waveform thin wire, and the chromosome model is annular iron wire.
The outer aperture of the connecting rod is exactly equal to the internal orifice dimension of tail neck model and caudal sheath model, and the outer aperture of projection is exactly equal to
Caudal sheath model lower end internal orifice dimension, the outer aperture of tailfiber model are exactly equal to the internal orifice dimension of groove.
The connecting rod and bacteriophage head model are structure as a whole, in the upper end circular hole of connecting rod insertion caudal sheath model,
In the lower end circular hole of projection insertion caudal sheath model, tailfiber model is screwed in groove.In tailfiber model lower end insertion circular hole, nucleic acid mould
Type is inserted in the connecting hole of nucleic acid model and head model, and chromosome model is put in cell model, is completed the phage and is inhaled
Attached Model Mounting.
The effect of technology of the present utility model：
Eight structures of this utility model represent bacteriophage head respectively, tail neck, caudal sheath, tailgate and anal spine, tailfiber, cell,
Bacteriophage nucleic acid, cell chromosome.By the displaying of 3-D solid structure, make observer be well understood to phage structure and
Suction type, books abstract figure is become more fully apparent, is deepened the impression.
