10.Biotechnology and its Application
normal
Tobacco plant resistant to a nematode have been developed by the introduction of $DNA$ that produces (in the host cells)
A
An antifeedant
B
Both sense and antisense $RNA$
C
$A$ particular hormone
D
Toxic protein
Solution
$A$ 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
