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.
