Adenine and Guanine belong to which class of nitrogenous bases?

Explanation:
Purines are one of the two classes of nitrogenous bases defined by their two-ring structure. Adenine and guanine are purines because each has a fused double-ring system. In contrast, pyrimidines have a single ring and include cytosine, thymine, and uracil. So adenine and guanine belong to the purines. Remember that a nucleotide is the base attached to a sugar and phosphate, and base pairs refer to how bases pair across strands (A with T/U, G with C), not to the basic classification of the base itself.
