Molymod DNA Double Helix Model, 22 Segments, miniDNA Kit

Simple differentiation of components by means of six easily distinguishable colours Representation of hydrogen bonds between thymine and adenine and the three hydrogen bonds between cytosine and guanine Representation of major and minor grooves on the surface of the double helix Purine bases (adenine guanine) and pyrimidine bases (cytosine thymine) differ in size Can be used to demonstrate DNA replication in model as well as complementary base pairing
