Vedclass · Answer

(A) The $Bt$ toxin genes are isolated from $Bacillus 	ext{ } thuringiensis$ and incorporated into several crop plants. Specifically, the genes $cry 	ext{ } I 	ext{ } Ac$ and $cry 	ext{ } II 	ext{ } Ab$ are incorporated into cotton to provide resistance against cotton bollworms. Similarly, the gene $cry 	ext{ } I 	ext{ } Ab$ is introduced into corn to protect it from the corn borer. Therefore, $cry 	ext{ } II 	ext{ } Ab$ controls cotton bollworms and $cry 	ext{ } I 	ext{ } Ab$ controls corn borer.
