Question

Select the wrong statement :-

• A. Human insulin is being commercially produced from a transgenic species of Escherichia coli.
• B. Genetically modified Bacillus thuringiensis is used as biopesticide on commercial scale
• C. Human protein, $\alpha$-1-antitrypsin, is used to treat emphysema
• D. Bt toxin genes cry IAC control com borer
• E. First transgenic cow, Rosie, produced $\alpha$-lactalbumin enriched milk

Answer 1

The correct option is D Bt toxin genes cry IAC control com borer

Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into several crop plants. The toxin is coded by a gene named cry. There are a number of them, for example, the proteins encoded by the genes cryIAc and cryIIAb control the cotton bollworms and cryIAb controls corn borer. Hence the statement in option D is wrong.

So the correct answer is option D.
