By Anne Marie Helmenstine, Ph.D. Nucleotide Definition: A nucleotide is an organic molecule made up of a nucleotide base, a five-carbon sugar (ribose or deoxyribose) and at least one phosphate group. Nucleotides make up the basic units of DNA and RNA molecules.
As such, a promoter is a sequence of nucleotides. A nucleotide is a molecule that is made up of a nitrogenous base, a pentose (5 carbon) sugar, and a phosphate group. The sequence of these nucleotides, differentiated by their nitrogenous bases (adenine, thymine, guanine and cytosine), will identify a promoter region.
