Identify the incorrect statement regarding Bacillus thuringiensis?
| 1. | forms protein crystals during a particular phase of their growth which contains a toxic insecticidal protein. |
| 2. | The Bt toxin protein exists as an inactive protoxin that is converted into an active form by an alkaline pH in the insect's gut. |
| 3. | Activated toxin binds to the surface of midgut epithelial cells, creates pores, causes cell swelling and lysis and eventually death of the insect. |
| 4. | Proteins encoded by the genes cryIAc and cryIIAb control the corn borer, that of cryIAb controls cotton bollworms. |
