Detailed explanation-1: -RNA interference also serves a role in protecting cells from viruses, by attacking their mRNAs and sometimes even their RNA-based genomes before the cell’s synthesis machinery can manufacture viral proteins.

Detailed explanation-2: -RNAi takes place in all eukaryotic organisms as a method of cellular defence. This method involves silencing of a specific mRNA due to a complementary dsRNA (infection by viruses or mobile genetic elements called transposons) molecule that binds to and prevents translation of the mRNA (silencing).

Detailed explanation-3: -RNA interference (RNAi) is an important defence against viruses and transposable elements (TEs). RNAi not only protects against viruses by degrading viral RNA, but hosts and viruses can also use RNAi to manipulate each other’s gene expression, and hosts can encode microRNAs that target viral sequences.
