Question

RNA interference (RNAi) is a process that results in

• A. Replication of mRNA
• B. Inhibition of translation of mRNA
• C. Synthesis of proteins at a faster rate
• D. Duplication of DNA

Hint:

RNAi is used in biotechnology to silence specific genes. Example: \[ \boxed{\text{RNAi in nematode-resistant tobacco plants}} \] Remember: \[ \boxed{\text{RNAi} \Rightarrow \text{Gene Silencing}} \]

Answer 1

The Correct Option is B

Step 1: Recall the concept of RNA interference. RNA interference (RNAi) is a biological process in which a specific mRNA molecule is silenced by complementary RNA molecules.

Step 2: Understand its mechanism. Double-stranded RNA (dsRNA) produces small interfering RNAs (siRNA), which bind to the target mRNA.

Step 3: Determine the effect. Binding of siRNA leads to degradation of mRNA or prevents its translation. Hence, \[ \boxed{\text{Translation of mRNA is inhibited}} \] Therefore, \[ \boxed{\text{(B)}} \] is the correct answer.
