MEDIUM
Assertion (A): cry is insect group specific gene of Bt cotton
Reason (R):  cry IAc and cry IIAb controls the cotton boll worms
EASY
Which of the following is the first step for genetically modifying an organism?
MEDIUM

Assertion (A): Bt toxin exists as inactive prototoxin but once an insect ingests the inactive toxin, it is converted into an active form of toxin.

Reason (R):  Protoxin gets activated in insect gut due to the acidic pH in the gut, which solubilises the protein crystals.
