What is true about Bt toxin?
1. The inactive protoxin gets converted into active form in the insect gut
2. Bt protein exists as active toxin in the Bacillus
3. The activated toxin enters the ovaries of the pest to sterilize it and thus prevent its
multiplication
4. The concerned Bacillus has antitoxins
