Question

How did the process of RNA interference help to control the nematode from infecting roots of tobacco plants? Explain.

Answer 1

RNA interference is the process to block gene expression in the parasites when enters into the host body.

Tobacco plants adapts this method to prevents the infection from nematodes. In this method complementry strands of RNA binds with single strand of mRNA which makes it double stranded RNA, as ds stranded RNA cannot translates so it blocks gene expression.

When nematodes injects its DNA into the tobacco plants, it produces two type of RNA sense and antisense. Theses two strands of RNA binds together to form ds RNA and causes RNA interference. Thus, this method helps to control nematodes from infecting roots of tobacco plants.
