Question:
The introduction of nematode-specific genes into host using Agrobacterium vectors causes the following action:
I. Formation of dsRNA.
II. Production of sense and antisense RNAs in the host cells.
III. RNA intermediate not formed.
IV. Silencing of specific mRNA of the nematode.

I. Formation of dsRNA.
II. Production of sense and antisense RNAs in the host cells.
III. RNA intermediate not formed.
IV. Silencing of specific mRNA of the nematode.
Show Hint
RNAi in plants involves sense and antisense RNA leading to silencing of target mRNA.

- II, III, IV
- I, II, III
- I, III, IV
- I, II, IV
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In gene silencing technology, the host plant produces both sense and antisense RNA strands which form dsRNA. This dsRNA does not proceed through a normal RNA intermediate and causes silencing of specific nematode genes through RNA interference. Hence II, III, and IV are valid consequences.
