Question

What are the type of nitrogenous base ? Also mention the type and number of bond between them. ​

Answer 1

Nitrogenous bases are split into two different types: the purines (adenine and guanine) and the pyrimidines (thymine, cytosine, and uracil). A purine will hydrogen-bond to a pyrimidine. Adenine always bonds with thymine (in DNA ) or with uracil (in RNA ) with two hydrogen bonds. Guanine will always bond with cytosine
