Answer:
(a) Bt corn. It is a type of genetically modified crop. It has been genetically modified through the addition of a small amount of genetic material from other organisms through molecular techniques.
(b) CryIAb gene codes for crystal protein. The Bt toxin protein exists as an inactive protein. On ingestion by an insect, the Bt toxin gets converted into an active form due to the alkaline pH of the gut which solubilizes the crystal. The activated toxin binds to the surface of mid gut and creates pores which cause death of the insect.
