The events occurring in the host cell on the introduction of nematode resistant gene into the tobacco plant by using Agrobacterium vectors are-
• The introduced DNA produces both sense and anti-sense RNA in the host cells.
• Since the sense and the anti-sense RNA are complementary to one another, they form a double stranded RNA (dsRNA).
• This initiates RNA interference, thereby silencing the mRNA of the nematode.
