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
Silencing of specific mRNA due to complementary RNA
Explanation
Solution
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.
