Question 62 : Cry II Ab and cry I Ab produce toxins that control

Question 63 : Assertion: A gene from <i>Bacillus thuringiensis</i> is incorporated in plant genome to increase yield Reason: It is Bt toxin producing gene which kills larvae of insects

Question 65 : Assertion: In $Bt$-cotton, $B.$ $thuringiensis$ produces a toxic insecticidal crystalline protein which destroys bollworms. Reason: $B.$ <b><i>thuringiensis</i></b> produces this toxic protein in an inactive form, but when an insect ingests this inactive protein, it is converted into an active form of toxin due to the alkaline pH of the gut which solubilises the crystals, which is responsible for the death of bollworm.
