MCQ
Q13. How does RNAi technology protect tobacco plants from nematodes?
  • A. By killing nematodes on contact
  • B. By producing antifungal proteins
  • C. By degrading nematode DNA
  • D. By silencing nematode mRNA using dsRNA
✅ Correct Answer: D

MCQ
Q4. Why can virus-free plants be regenerated from infected ones using meristem culture?
  • A. Meristem contains virus-neutralising proteins
  • B. Viruses cannot infect rapidly dividing cells
  • C. Meristem lacks genetic material
  • D. Viruses fail to invade meristematic regions
✅ Correct Answer: D
Meristematic tissues are usually free of viruses and thus are used to obtain virus-free plants in tissue culture.
