Which of the following specific nitrogenous bases strictly and chemically belongs to the Pyrimidine — Biomolecules Chemistry Question

💡 Solution & Explanation

Pyrimidines are strictly single-ringed nitrogenous bases. Cytosine ($C$), Thymine ($T$), and Uracil ($U$) represent the pyrimidines. However, Uracil is exclusively localized within RNA molecules. Thymine is the exact pyrimidine firmly native exclusively to DNA structure. Adenine and Guanine are double-ring purines.
