CG DNA/RNA Base Pair

This image shows cytosine & guanine paired, left & right respectively. The purine cytosine's double bonds are on the underside. The pyrimidine guanine's double bonds are shown on the 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.
