nu·cle·o·tide

 (no͞o′klē-ə-tīd′, nyo͞o′-)
n.
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.]

nucleotide

(ˈnjuːklɪəˌtaɪd)
n
(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-)

n.
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.

nu·cle·o·tide

(no͞o′klē-ə-tīd′)
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.
