Question

What is the consequence when the nematode's essential mRNA is silenced by RNAi?

Options

• The nematode reproduces more rapidly

• The nematode cannot synthesize vital proteins and is unable to live in the transgenic host

• The nematode develops resistance to the plant

• The nematode's genes mutate and adapt

Answer 1

Because the nematode's specific mRNA is neutralized or silenced, the nematode cannot synthesize vital proteins that are essential for its survival. As a result, the parasite is unable to live in the transgenic host and the tobacco plant is protected from the nematode infection.
