Biotechnology and its Applications

170935 Bacillus thuringiensis forms protein crystals which contain insecticidal protein

1 does not kill the carrier bacterium which is itself resistant to this toxin
2 binds with epithelial cells of midgut of the insect pest ultimately killing it
3 is coded by several genes including the gene CRY
4 is activated by acid $\mathrm{pH}$ of the foregut of the insect pest
