Def of nitrogen base
WebThe DNA molecule consists of 4 nitrogen bases, namely adenine (A), thymine (T), cytosine (C) and Guanine (G), which ultimately form the structure of a nucleotide. The A and G are purines, and the C and T are pyrimidines. The two strands of DNA run in opposite directions. These strands are held together by the hydrogen bond that is present ... WebThe pyrimidine and purine bases shown in Figs. 6.2 and 6.3 correspond to the ketone or lactam forms of these nucleotides, which predominate in natural products. The enol or lactim forms of these nucleotides exist in much lower proportion in nature. These are isomers that result from the displacement of the hydrogen atom bound to nitrogen toward the oxygen.
