Question

Assertion (A): Hirudin is a type of protein that prevents blood clotting.

Reason (R): The gene that encodes hirudin is transferred into Brassica napus, where hirudin is accumulated in the seeds.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

Explanation:

Hirudin prevents blood clotting, and the hirudin gene can be introduced into Brassica napus, where the protein accumulates in seeds. The reason describes how hirudin is produced; it does not explain its blood-clotting function.
