(nucleotide biosynthesis process) Nucleotide Biosynthesis consists of activities of biologic molecules or complexes involved in the enzymatic formation of nucleoside phosphates, the monomeric building blocks from which DNA or RNA polymers are constructed.

(nucleotide biosynthetic process) The chemical reactions and pathways resulting in the formation of nucleotides, any nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic-nucleotides (nucleoside cyclic phosphates).
