Question

RNA interference involves

• A. Silencing of specific mRNA due to complementary RNA
• B. Interference of RNA in synthesis of DNA
• C. Synthesis of mRNA from DNA
• D. Synthesis of cDNA from RNA using reverse transcriptase

Answer 1

Answer: (A)

RNA interference (RNAi) is the phenomenon of inhibiting activity of a gene through production of both sense and antisense RNA. RNAi takes place in all eukaryotic organisms as a method of cellular defense. This method involves a specific mRNA silencing. It is due to a complementary dsRNA molecule which binds to and prevents translation of the mRNA causing its silencing.
