Question

Assertion (A) : The milk produced by transgenic cow 'Rosie' was nutritionally more balanced product for human babies than natural cow milk.
Reason (R) : It was human protein enriched milk containing human alpha lactalbumin.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

Remember the year (1997) and the specific protein concentration ($2.4 \text{ g/L}$ of alpha-lactalbumin) for Rosie's milk.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This question concerns the applications of transgenic animals in biotechnology for improving nutritional quality.
Step 2: Detailed Explanation:
In 1997, the first transgenic cow, Rosie, was produced.
Standard cow milk is not ideal for human infants as it contains different protein ratios.
Rosie's milk was engineered to contain the human protein alpha-lactalbumin (\(2.4\) grams per litre).
This made the milk nutritionally superior and more balanced for human babies compared to natural cow milk.
Assertion (A) is true.
Reason (R) is true and it explains \textit{why} the milk was more balanced (due to the specific human protein enrichment).
Step 3: Final Answer:
Both statements are true, and R is the correct explanation of A. Hence, option (A) is correct.
