The nitrogen base pictured is adenine. Is this nucleotide considered a purine or a pyrimidine? There is a molecule, a base of which is formed by 2 fused rings, each of which contains 2 nitrogen atoms in their structure. One ring is five-membered while the other is a six-membered ring. The nitrogen base pictured is adenine. Is this nucleotide considered a purine or a pyrimidine? a. purine b. pyrimidine

Purine

Explanation:

A purine is a nitrogenous base found in nucleic acids, and contains a 6-membered pyrimidine ring fused to the 5-membered imidazole ring. The most common examples of purine bases are adenine and guanine.

Thus, the nitrogen base pictured is adenine, and the nucleotide considered is a purine
