Solution
In RNAi genes are silenced using ds RNA.
Explanation:
RNAi is a cellular defense mechanism found in all eukaryotic species. This method involves the silencing of a specific mRNA by a complementary ds RNA molecule binding to the mRNA and preventing it from being translated (silencing). Infection with viruses with RNA genomes or mobile genetic elements (transposons) that replicate via an RNA intermediary could be the source of this complementary RNA.
