Verified by Experts

The correct answer is:

False – Meloidogyne incognita infects the roots, not the stems.

False – The nematode does not cause DNA silencing; RNA interference (RNAi) in the plant silences the nematode's gene expression.

True – The transgene is introduced into plant cells using the vector Agrobacterium tumefaciens.

True – The transgenic plant produces both sense and antisense RNA of a nematode gene, forming dsRNA and triggering RNAi.
