Statement I: Bt toxins are specific to certain insect groups and are encoded by the cry gene family, such as cryIAc.
Statement II: Bt toxin is initially inactive (protoxin) within Bacillus thuringiensis. Upon ingestion by an insect, the alkaline pH of the gut activates the protoxin.
Choose the correct answer:
Both Statement I and Statement II are true.
Statement I is true but Statement II is false.
Statement I is false but Statement II is true.
