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.
