nu·cle·o·tid·yl·trans·fer·as·es

(nū'klē-ō-tī'dĭl-trans'fĕr-ās'ĕz),
Enzymes that catalyze the transfer of transferring nucleotide residues (nucleotidyls) from nucleoside di- or triphosphates into dimer or polymer forms. Some nucleotidyltransferases bear specific names (for example, adenylyltransferases), trivial names indicating the linkage hydrolyzed in the synthesis (pyrophosphorylases, phosphorylases), or names indicating the material that is synthesized (for example, RNA or DNA polymerase).

RNA polymerase

n.
A polymerase that catalyzes the synthesis of a complementary strand of RNA from a DNA template, or, in some viruses, from an RNA template.
