Question
Two statements are given below, one labelled as
Assertion (A) and other as Reason (R). Assertion (A): Insect resistant transgenic cotton varieties has been produced by transfering the cry gene. Reason (R): The cry gene is derived from bacterium. Choose the correct answer from the codes given below.Solution
The assertion that insect-resistant transgenic cotton varieties have been produced by transferring the cry gene is correct, and the reason that the cry gene is derived from the bacterium Bacillus thuringiensis, which is also correct and explains why the cotton is resistant to certain pests.
