User:Wayne Decatur/Suppression of RNA Silencing by Viruses: Difference between revisions

RNA interference (RNAi) or post-transcriptional gene silencing (PTGS) or RNA silencing is an evolutionarily conserved cellular response to the presence of double-stranded (ds) RNA that functions as a gene inactivation system in many eukaryotes and relies on tiny RNAs as the targeting molecules. One function of RNA silencing is to act in surveillance against molecular parasites, such as viruses, several of which rely on double-stranded RNA for replication.
