  1. RNA interference involves
    1. Synthesis of mRNA from DNA
    2. Synthesis of cDNA from RNA using reverse transcriptase
    3. Silencing of specific mRNA due to complementary RNA
    4. Interference of RNA in synthesis of DNA
Correct Option: C

RNAi is a method of cellular defense in all eukaryotes. It is a system within living cells that helps to control the activity of specific genes. This method involves silencing of mRNA due to complementary double stranded RNA that prevents translation of target gene or mRNA [silencing]. Source of ds RNA is retrovirus (having RNA genome) or transposons (mobile genetic material).
