Question

The Bt toxin in genetically engineered Bt cotton kills the pest by:

• A. Creating pores in the midgut
• B. Damaging the respiratory system
• C. Degenerating the nervous system
• D. Altering the pH of body fluids

Answer 1

The Correct Option is A

The Bt toxin produced by Bacillus thuringiensis in genetically modified Bt cotton primarily kills pests by creating pores in their midgut. This disruption of the gut lining leads to the death of the insect pest.
