RNA interference involves the:
Correct answer: B. Silencing of specific mRNA due to complementary RNA
- A. Synthesis of complementary DNA and RNA using reverse transcriptase
- B. Silencing of specific mRNA due to complementary RNA
- C. Interference of RNA in the synthesis of DNA
- D. Synthesis of mRNA from DNA
Explanation
RNA interference (RNAi) is the phenomenon of inhibiting the activity of a gene through the production of both sense and antisense RNA. RNAi takes place in all eukaryotic organisms as a method of cellular defense. This method involves specific mRNA silencing. It is due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA causing its silencing.
