Question

Assertion (A): Rosie was the first transgenic cow to make more nutritionally balanced milk for consumption by human babies.

Reason (R): The milk of Rosie the cow contained human beta-lactalbumin, which made the milk rich in protein.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true and R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

Assertion (A) is true because Rosie was the first transgenic cow engineered to produce milk that was nutritionally more suitable for human infants.

Reason (R) is false because Rosie’s milk contained human α-lactalbumin, not β-lactalbumin.

Since the protein mentioned in R is incorrect, the reason does not support the assertion.
