A nucleotide is made of a phosphate, a molecule of ribose or 2'-deoxyribose, and another molecule called a nitrogenous base. The initial letters of the base names that spell out the genetic code. A, T, G, and C stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.

Thymine
Thymine is also known as 5-methyluracil. As a pyrimidine nucleobase, thymine is a heterocyclic aromatic organic compound. Thymine may be derived by methylation of uracil at the fifth carbon.
Thymine combined with deoxyribose creates the nucleoside deoxythymidine, which is also know as thymidine. Thymidine can be phosphorylated with phosphoric acid groups, creating Thymidinemonophosphate (TMP), Thymidinediphosphate (TDP) or Thymidinetriphosphate (TTP).
