(i) What does happen when Meloidogyne incognita consumes cells with RNAi gene?

(ii) How Agrobacterium vectors are useful in genetic engineering?

Answer:

(i) When Meloidogyne incognita consumes cells with RNA; gene, its mRNA is destroyed. This results in the death of the parasite in the transgenic host.

(ii) Agrobacterium is effectively used as a vector for the transfer of genes of interest into plant cells. It is infact called a natural genetic engineer because genes carried by its plasmid produce effect in several parts of the plan.
