A Nucleotide with a Single Cyclic Ring Structure is a Pyrimidine

Question

A nucleotide with a single cyclic ring structure is a pyrimidine.

Accepted Answer

Pyrimidines, such as cytosine, thymine, and uracil, have a single ring structure, while purines, such as adenine and guanine, have a double ring structure. Nucleotides are the building blocks of DNA and RNA, and they are made up of a nitrogenous base (pyrimidine or purine), a phosphate group, and a sugar molecule.
