Options
- AAll are incorrect
- BOnly 3 is correct
- CBoth 2 and 3 are correct
- DBoth 3 and 4 are incorrect
Correct answer
C. Both 2 and 3 are correct
Step-by-step solution
Some strains of Bacillus thurengeneis produce proteins that kill certain insects such as lepidopterans, coleopterans and dipterans. B. thurengeneis forms protein crystals during a particular phase of their growth, these crystals contain a toxic insecticidal protein. The activated toxin binds to the surface of midgut epithelial cells and create pores that cause cell swelling and lysis and eventually cause death of the insect.
