 (rĕp′lĭ-kās′, -kāz′)
Any of various enzymes that catalyze the synthesis of an RNA molecule from an RNA template (as in a virus) or a DNA molecule from a DNA template.


(ˈrɛplɪˌkeɪs; ˈrɛplɪˌkeɪz)
any enzyme that catalyses the replication of RNA

RNA synthetase

an enzyme that catalyzes the synthesis of RNA in cells infected with RNA viruses, allowing production of copies of the viral RNA. Also called replicase.

Cellular mechanisms translate the viral structural and nonstructural proteins from the viral RNA, and the RNA is replicated by the viral replicase in conjunction with cellular factors.
The process starts when the virus produces replicase and once the translation inside the cell has taken place, the replicase is translated and any further translation is stopped by a stop codon.
