Definition of Nucleotide

1. Noun. A phosphoric ester of a nucleoside; the basic structural unit of nucleic acids (DNA or RNA).


Definition of Nucleotide

1. Noun. (biochemistry) the monomer comprising DNA or RNA biopolymer molecules. Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA); and a phosphate group. ¹

Medical Definition of Nucleotide

1. Phosphate esters of nucleosides. The metabolic precursors of nucleic acids are monoesters with phosphate on carbon 5 of the pentose (known as 5' to distinguish sugar from base numbering). However many other structures, such as adenosine 3'5' cyclic monophosphate (cAMP) and molecules with 2 or 3 phosphates are also called nucleotides.
