Question

RNA interference (RNAi) helps in making tobacco-plant resistant to a nematode (Meloidegyne incognita)

Choose the correct option that shows how RNAi is achieved:

(A) Preventing the process of translation of mRNA of the nematode.

(B) Preventing the process of replication of DNA of the nematode.

(C) Preventing the process of transcription of DNA of the plant.

(D) Preventing the process of replication of DNA of the plant.

Answer 1

Correct option is: (A) Preventing the process of translation of mRNA of the nematode.  

RNAi involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA. So, the translation of mRNA of the nematode is prevented.
