The primary structure of a purine is two carbon-nitrogen rings. Cytosine, thymine, and uracil are classified as pyrimidines which have a single carbon-nitrogen ring as their primary structure (Figure 1.1. 1 ). Each of these basic carbon-nitrogen rings has different functional groups attached to it.
