Tobacco plants resistant to a nematode have been developed by the introduction of DNA that produces (in the host cells):

Question

Accepted Answer

both sense and anti-sense RNA. The resistant tobacco plants were engineered to produce both sense and antisense RNA, which form double-stranded RNA. This activates RNA interference in the nematode, silencing a vital gene and preventing infection.
