Given below are two statements regarding the development of pest-resistant plants : Statement I : Nematode-specific genes were introduced into the host plant using Agrobacterium vectors to develop resistance against Meloidogyne incognita . Statement II : The introduction of DNA was such that it produced only the antisense RNA in the host cells to initiate RNA interference (RNAi). In the light of the above statements,

Options

  1. ABoth Statement I and Statement II are correct
  2. BBoth Statement I and Statement II are incorrect
  3. CStatement I is correct but Statement II is incorrect
  4. DStatement I is incorrect but Statement II is correct

Correct answer

C. Statement I is correct but Statement II is incorrect

Step-by-step solution

Statement I is correct. Nematode-specific genes were introduced into the host plant (tobacco) using Agrobacterium vectors to develop resistance against the nematode Meloidogyne incognita. Statement II is incorrect. The introduction of DNA was such that it produced both sense and antisense RNA in the host cells. These two RNAs, being complementary to each other, formed a double-stranded RNA (dsRNA) that initiated RNA interference (RNAi) and thus silenced the specific mRNA of the nematode. Therefore, Statement I is c
