(A) : The Bt toxin proteins exist as inactive protoxins.
(R) : It is converted into an active form of toxin by the acidic pH of the gut of the insect.

How is Bt toxin converted into active form?

Bt toxin protein exist in which form.

Consider the following statements. A. Bt toxin is produced by a bacterium called Bacillus thuringiensis. B. The Bt toxin is coded by a gene named cry. C. Bt inactive toxin is converted into an active form of toxin due to the acidic pH of the insect gut. D. The Bt proteins encoded by the genes cryIAc and cryIIAb control the corn borer. Of the above statements:

The inactive protoxin is activated in the gut of the insect by :

The inactive protoxin is activated in the gut of the insect by :

The inactive protoxin is activated in the gut of the insect by :

The inactive protoxin is activated in the gut of the insect by :

Assertion: Crystal protein does not kill the Bacillus & kill only insect Reason :In Bacillus it exist as inactive proteins but in insect it is converted into an active form due to acidic pH of the gut
