Question

What is a natural process in which cells evolved to destroy RNA-based viruses?

Answer 1

RNA interference:

1. It is a natural mechanism of defense in eukaryotes by which small RNA silences the expression of viral genes in the host.
2. RNA interference is called gene silencing as the expression of viral mRNA is silenced by a small class of RNA found in the genome of eukaryotes.
3. Small interference RNA (siRNA) suppresses the genes of RNA-based viruses.
