RNAdependent
RNA-dependent is an adjective used in molecular biology to describe enzymes or processes that use RNA as a template or substrate to synthesize RNA. The term is most commonly encountered in reference to RNA-dependent RNA polymerases, a class of enzymes that catalyze RNA synthesis using an RNA template.
RNA-dependent RNA polymerases (RdRPs) are central to the replication of RNA viruses, which lack a DNA stage
In addition to viral roles, RNA-dependent RNA polymerases participate in RNA silencing pathways in some eukaryotes,
The study of RdRPs encompasses structure, catalysis, and evolution. They are a notable exception to the general
