347687 Read the following statements and select the correct option
I. Recombinant DNA technology is used to improve crop plants by increasing their productivity, by making them more nutritious and by developing disease resistant.
II. Bt cotton is resistant to bollworm infestation.
III. Bacillus thuringiensis
form cry protein during any phase of their growth
IV. Bacillus thuringiensis
is not harmed by self Cry protein because of its occurrence as protoxin (inactive)
V. Protoxin Cry protein is changed into active Cry protein in the stomach of insects due to alkaline \(\mathrm{pH}\) in stomach
