A compact molecular model kit to make two base pairs, thymine-adenine and cytosine-guanine with ribose-phosphate chains. The two layer molecular model kit is self-assemble. Layers are supported on a small stand and models can be easily dismantled to keep as units in a supplied storage box. The two layer molecular model kit includes 128 atom parts, 110 links, 1 tool, and stand. The molecular model displays the molecular structure of thymine-adenine and cytosine-guanine.
