Q. Tobacco plant resistant to a nematode have been developed by the introduction of DNA that produces (in the host cells)
A) An antifeedent
B) Both sense and antisense RNA
C) A particular hormone
D) Toxic protein
Explanation
A nematode Meloidegyne incognitia infects the roots of tobacco plants, which reduces the production of tobacco. It can be prevented by using RNA interference process. In this process, by using Agrobacterium vector, nematode specific genes were introduced into the host plants, which produced both sense and antisense RNA in the host cells
