In RNA interference method, nematode specific genes were introduced into the host plant which produce _________

A only sense strand of RNA in the host
B only antisense strand of RNA in the host
C both sense and antisense strands of RNA in the host
D dsDNA for cellular defense

Verified Solution

Answer & Solution

Correct Answer

(C) both sense and antisense strands of RNA in the host

Step-by-step Solution

Detailed explanation

In the RNA interference method, the host plant is engineered to produce RNA molecules that are complementary to the nematode's target mRNA. These engineered constructs typically lead to the production of both sense and antisense RNA strands, which then anneal to form…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
