MCQ
$RNA$ interference involves
  • A
    synthesis of $cDNA$ and $RNA$ using reverse transcriptase
  • ✓
    silencing of specific $mRNA$ due to complementary $RNA$
  • C
    interference of $RNA$ in synthesis of $DNA$
  • D
    synthesis of $mRNA$ from $DNA$
✓

Answer

Correct option: B.
silencing of specific $mRNA$ due to complementary $RNA$
b
(b) : $RNA$ 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.
