Detailed explanation-1: -RNA interference (RNAi) refers to the ability of double-stranded RNA molecules to cause sequence-specific degradation of single stranded RNAs such as messenger RNAs and viral RNAs in vivo. RNAi is an ancient mechanism of gene regulation, genome maintenance and antiviral defense found in all eukaryotes.

Detailed explanation-2: -RNA interference (RNAi) is a post-transcriptional, highly conserved process in eukaryotes that leads to specific gene silencing through degradation of the target mRNA. This mechanism is mediated by double-stranded RNA (dsRNA) that is homologous in sequence to the silenced gene.

Detailed explanation-3: -In insects, the RNA interference (RNAi) pathway plays a major role in antiviral responses, as shown against many RNA viruses. The response includes the cleavage of double-stranded RNA genome or intermediates, produced during replication, into viral short interfering RNAs (v-siRNAs).
