Question

Assertion :The milk of transgenic cow Rosie was nutritionally more balanced than normal cow milk. Reason: $\alpha$-1 antitrypsin is a biological product produced by transgenic animals.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

In 1997, Rosie, the first transgenic cow, was engineered to produce milk enriched with a human protein called alpha-lactalbumin, making it more nutritionally balanced than natural cow's milk and suitable for babies and elderly people with special nutritional or digestive needs.

• The transgenic sheep Tracy was developed by genetic modification to produce the protein alpha 1 antitrypsin in the milk. This is the human protein whose gene was introduced in the sheep for the commercial production of the protein which can be used for the treatment of the respiratory infections.
• So the assertion and reason are both correct but the reason is not the correct explanation of the reason.
• Hence the correct answer is option B.
