A purine is a heterocyclic aromatic organic compound. It consists of a pyrimidine ring fused to an imidazole ring. Purines, which include substituted purines and their tautomers, are the most widely occurring nitrogen-containing heterocycle in nature.Purines and pyrimidines make up the two groups of nitrogenous bases, including the two groups of nucleotide bases.wo of the five bases in nucleic acids, adenine (2) and guanine (3), are purines. In DNA, these bases form hydrogen bonds with their complementary pyrimidines thymine and cytosine, respectively.
A DNA nucleotide is one of two kinds of bases... a pyrimidine or a purine. The purine is a heterocyclic (two-ring) molecule with a 5 member and 6 member ring each containing 2 â¦ Nitrogens.Purines are just a single ring with 2 Nitrogens.Each base is paired with a sugar (ribose) less one oxygen (hence the prefix de-oxyribose).here are four nucleotides that make up DNA: Adenine, Thymine, Guanine and Cytosine. There are billions of them that make up one strand of DNA. Adenine always pairs with Thymi â¦ ne and Guanine always pairs with Cytosine.
