The purine bases in dna are
WebbPurines, pyrimidines, nucleosides, and nucleotides belong to a biologically important class of compounds in which several of these derivatives constitute nucleic acid components (typical structures of these compounds are given in Figure 1 ). Purines and pyrimidines are azaheterocyclic bases. WebbThe most important biological substituted purines are adenine and guanine, which are the major purine bases found in RNA and DNA. In DNA, guanine and adenine base pair (see …
