Question

What are two types of nitrogenous bases found in nucleic acids?

Answer 1

You mean purines and pyrimidines??

Explanation:

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. Note that the bonding can happen vice-versa as well.
