1.	Assertion A crop expressing a cry gene is usually resistant to a group of insects. Reason Cry protein produced from Bacillus thuringiensis is toxic to larvae of certain insects.A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.B. Both Assertion and Reason are true, but Reason is not the correct explanation of AssertionC. Assertion is ture, but Reason is false.D. Assertion is false, but Reason is true.
Answer» Correct Answer - A Bacillus thuringiensis (Bt), a soil bacterium produces a Cry protein (crystal protein ). This protein is toxic to larvae of certain insects. There are several kinds of Cry proteins. Each Cry protein is toxic to a different group of insects. The gene encoding Cry protein, that is cry gene has been isolated and transferred into several crops. A crop expressing a cry gene is usually resistant to the groups of insects.
