nucleotide(redirected from Deoxynucleotides-triphosphate)
Also found in: Thesaurus, Medical, Encyclopedia.
Any of a group of compounds consisting of a nucleoside combined with a phosphate group and constituting the units that make up DNA and RNA molecules.
[Alteration of nucleoside.]
(Biochemistry) biochem a compound consisting of a nucleoside linked to phosphoric acid. Nucleic acids are made up of long chains (polynucleotides) of such compounds
[C20: from nucleo- + t (added for ease of pronunciation) + -ide]
nu•cle•o•tide(ˈnu kli əˌtaɪd, ˈnyu-)
any of a group of molecules that, when linked together, form the building blocks of DNA or RNA: in DNA the group comprises a phosphate group, the bases adenine, cytosine, guanine, and thymine, and a pentose sugar; in RNA the thymine base is replaced by uracil.
[< German Nucleotid (1908)]
Any of a group of organic compounds composed of one of several nitrogen bases linked to a sugar and a phosphate group. The nucleic acids DNA and RNA are made up of chains of nucleotides. See Note at DNA.
