Nucleotide - Wikipedia
A nucleotide is composed of three distinctive chemical sub-units: a five-carbon sugar molecule, a nitrogenous base—which two together are called a nucleoside—and one phosphate group.With all three joined, a nucleotide is also termed a "nucleoside monophosphate".The chemistry sources ACS Style Guide and IUPAC Gold Book prescribe that a nucleotide should contain only one phosphate group, but ...

Nucleotide Definition. A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions.A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base.The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
