NEETZoologyBiotechnology and Its Applications
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In transgenic tobacco plants developed using RNA interference, the parasite Meloidogyne incognita cannot survive. Reason (R): The specific mRNA of the nematode is silenced by the complementary dsRNA produced in the host plant, preventing translation of an essential protein. In the light of the abov
Options
- ABoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- B(A) is correct but (R) is not correct
- CBoth (A) and (R) are correct and (R) is the correct explanation of (A)
- D(A) is not correct but (R) is correct
Correct answer
C. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
Assertion (A) is correct because RNA interference (RNAi) is a strategy used to develop transgenic tobacco plants that are resistant to the nematode Meloidogyne incognita. The parasite cannot survive in these transgenic hosts. Reason (R) is correct and provides the correct explanation for (A). In the RNAi process, nematode-specific genes are introduced into the host plant, producing both sense and anti-sense RNA. These two RNAs being complementary to each other form a double-stranded RNA (dsRNA) that initiates RNAi
