RNA interference which is employed in making tobacco plant resistant to Meloidgyne incognita is essentially involved in

A preventing the process of replication of DNA
B preventing the process of translation of mRNA
C preventing the process of splicing of hnRNA
D preventing the process of transcription

Verified Solution

Answer & Solution

Correct Answer

(B) preventing the process of translation of mRNA

Step-by-step Solution

Detailed explanation

(B) preventing the process of translation of mRNA,
RNA interference method involves participation of a long double stranded RNA (dsRNA) to silence the expression of target genes.

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.
