RNA viruses rely primarily on low-fidelity replication by RNA-dependent RNA polymerases (RdRps) to facilitate viral adaptation to complex host environments. This occurs in negative strand RNA viruses and dsRNA viruses, both of which exist for a portion of their life cycle as double-stranded RNA. RNA-dependent RNA polymerase or RNA replicase is an enzyme that catalyzes the replication of RNA from an RNA template. Soc., 88, 3150 (1966).
