This image shows guanine & cytosine paired, left & right respectively. The pyrimidine guanine's double bonds are on the underside. The purine cytosine's double bonds are shown topside.
The X-pegs are used with planar trigonal atoms to indicate double bonds and help illustrate the anti-parallel nature of the double helix. This feature of the Indigo DNA bases & 12 base pair DNA model is unique and helps ensure proper construction of the model.
Note: the 2 deoxyribose or ribose phosphates are not included but can be added to the shopping cart from the Related Products section below.
