Tobacco plants resistant to a nematode have been developed by the introduction of DNA that produce (in the host cells)
Options:
Answer:
D
Solution:
UsingAgrobacteriumvectors, nematode-specific genes were introduced into the host plant. The introduction of DNA was such that it produced both sense and anti-sense RNA in the host cells. These two RNAs being complementary to each other formed a double-stranded (dsRNA) that initiated RNAi and thus, silenced the specific mRNA of the nematode.
