A pyrimidine is a nucleotide (nucleoside + phosphate group) whose basic structure is cyclohexane with Nitrogen atoms positioned at 1 and 3. This molecule is also aromatic, ... Pyrimidine. Two of the bases found in DNA, cytosine (C) and thymine (T), and a base found only in RNA, uracil (U), are derivatives of pyrimidine.

Each nucleotide consists of the pentose sugar deoxyribose, a phosphate group and a nitrogenous base which may be either a purine or a pyrimidine. Deoxyribose and a nitrogenous base together form a nucleoside. A nucleoside and a phosphate together form a nucleotide.
