Question

Assertion (A): Restriction enzymes cut the strand of DNA to produce sticky ends.

Reason (R): Stickiness of the ends facilitates the action of the enzyme DNA polymerase.

विकल्प

• 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

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

Explanation:

Restriction enzymes can cut DNA to leave sticky ends. Their stickiness facilitates DNA ligase action, not DNA polymerase action, so the reason is false.
