Name the insect pest that is killed by the products of cryIAc gene. Explain how the gene makes the plant resistant to the insect pest.
a. cryIAc gene codes for a toxic insecticidal protein that controls the cotton bollworms.
b. This gene codes for a toxin that becomes active when ingested by the insect. The activated toxin binds to the surface of mid-gut epithelial cells thus creating pores which causes cell swelling and lysis, further leading to death of the insects.
