DNA model, 22 layers
This DNA model makes it easier to study the double helix structure.
The model contains 22 base pairs consisting of:
12 thymine (T) (orange), 11 adenine (A) (blue), 11 guanine (G) (green),11 cytosine (C) (yellow).
Deoxyribose (red) and phosphate (purple) are also included.
The model can be mounted on the supplied holder with foot and top or it can be assembled without a holder and spread out flat.
1cm = 2 Angstroms.
Base parts are designed so that only the corresponding bases can be put together, i.e. T fits A and C fits G.
