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 of Nucleotide at Dictionary.com
Nucleotide definition, any of a group of molecules that, when linked together, form the building blocks of DNA or RNA: composed of a phosphate group, the bases adenine, cytosine, guanine, and thymine, and a pentose sugar, in RNA the thymine base being replaced by uracil. See more.

Nucleotide: Definition, Structure (3 Parts), Examples ...
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.
Nucleotide - ncbi.nlm.nih.gov
A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.
Nucleotide | biochemistry | Britannica.com
Nucleotide: Nucleotide, any member of a class of organic compounds in which the molecular structure comprises a nitrogen-containing unit (base) linked to a sugar and a phosphate group. The nucleotides are of great importance to living organisms, as they are the building blocks of nucleic acids, the substances

Nucleotide | Definition of Nucleotide by Merriam-Webster
Nucleotide definition is - any of several compounds that consist of a ribose or deoxyribose sugar joined to a purine or pyrimidine base and to a phosphate group and that are the basic structural units of nucleic acids (such as RNA and DNA).
Nucleoside vs Nucleotide - Difference and Comparison | Diffen
What's the difference between Nucleoside and Nucleotide? A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups. Nucleoside =...
