Q. Protein encoded by gene cry $I \,AB$ controls the infestation of which of the following insects

AMUAMU 2014Biotechnology and its Applications

Solution:

The most $Bt$ toxins are insect groups specific. The toxin is coded by a gene called cry. There are many such genes. For example, the proteins encoded by cry $I \,Ab$ controls the corn borer infestation and cry $I \,Ac$ and Cry if $Ab$ control the cotton bollworms.
