nucleotide (redirected from Nucleotides)

nucleotide /nu·cleo·tide/ (noo´kle-o-tīd″) one of the compounds into which nucleic acid is split by action of nuclease; nucleotides are composed of a base (purine or pyrimidine), a sugar (ribose or deoxyribose), and a phosphate group.

---

cyclic nucleotides  those in which the phosphate group bonds to two atoms of the sugar forming a ring, as in cyclic AMP and cyclic GMP, which act as intracellular second messengers.

nu·cle·o·tide (nkl--td)

n.

Any of various compounds consisting of a nucleoside combined with a phosphate group and forming the basic constituent of DNA and RNA.

nucleotide

[no̅o̅′klē·ətīd′]

a compound consisting of one or more phosphate groups, a pentose sugar, and a nitrogenous base. Chains of nucleotides form DNA and RNA; free nucleotides, such as adenosine triphosphate and guanosine triphosphate, are important energy carriers in all cells.

nucleotide [noo´kle-o-tīd]

any of a group of compounds obtained by hydrolysis of nucleic acids, consisting of a purine or pyrimidine base linked to a sugar (ribose or deoxyribose), which in turn is esterified with phosphoric acid.

cyclic n's those in which the phosphate group bonds to two atoms of the sugar forming a ring, as in cyclic AMP and cyclic GMP, which act as intracellular second messengers.

single nucleotide polymorphisms (SNPs)

single base pair changes that distinguish one individual from another of the same species.
