Silencing of mRNA has been used in producing transgenic plants resistant to: A Bollworms B Nematodes C White rusts D Bacterial blights
Correct answer is option B. Explanation for correct option: RNA interference is the process in which the gene expression is inhibited by RNA molecules by neutralizing the targeted mRNA molecules. Nematode-specific gene was introduced into tobacco plant via Agrobacterium vector. The introduced DNA produced both sense and antisense RNA which were complementary to each other and formed dsRNA. This RNA interference caused the silencing of nematode-specific mRNA and was lethal for the survival of nematode in tobacco root cells. Transgenic tobacco plants were nematode-resistant due to RNA interference.
