Text Solution

Verified by Experts

The correct answer is:

The process uses Agrobacterium vectors to insert nematode-specific genes into the host plant. This leads to the production of sense and anti-sense RNA, which combine to form double-stranded RNA (dsRNA). This dsRNA triggers RNA interference, silencing the corresponding nematode mRNA and disrupting its essential functions. As a result, the nematode cannot survive in the transgenic host, providing effective protection for the plant against the parasite.
