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.

RNA polymerase

an enzyme that catalyzes the assembly of ribonucleoside triphosphates into RNA, with single-stranded DNA serving as the template. Also called RNA nucleotidyltransferase.

RNA polymerase

An enzyme that catalyses the joining of appropriate NUCLEOTIDES to form a molecule of RNA, using DNA as a template.

RNA polymerase

one of several enzymes that catalyses the formation of RNA molecules from DNA templates during TRANSCRIPTION. see OPERON MODEL.

polymerase

an enzyme that catalyzes polymerization, particularly of nucleic acids.

polymerase chain reaction
see pcr1.
RNA polymerase
1. an enzyme that synthesizes an RNA copy of the sequence in a limited region of DNA in a process known as DNA transcription. Called also DNA-dependent RNA polymerase.
2. a viral enzyme that synthesizes RNA from an RNA template during viral replication. Called also RNA-dependent RNA polymerase.
RNA-dependent RNA polymerase
see RNA polymerase (above).
Taq polymerase
a DNA polymerase that functions at high temperature; derived from the bacterium Thermus aquaticus and used in the polymerase chain reaction.
