Q. The proteins encoded by the genes cryIAc and cryIIAb control

JIPMERJIPMER 2015Biotechnology and its Applications

Solution:

Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into several crop plants such as cotton. Two cry genes, cryIAc and cryIIAb have been incorporated in cotton. The genetically modified crop is called Bt cotton as it contains Bt toxin genes against cotton bollworms.
