TA DNA Base Pair

This image shows the thymine and adenine nucleic acid bases, paired, left & right respectively. The purine thymine's double bonds are on the underside and the pyrimidine adenine'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 is a unique feature of Indigo® DNA base pairs as used in the 12 base pair DNA model helps ensure proper construction of the model.
