Question

Assertion (A): DNA fingerprinting is applied in paternity testing in case of disputes.

Reason (R): It employs the principle of polymorphism in DNA sequences as the polymorphisms are inheritable from parent to children.

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, and reason is the correct explanation of assertion.

Explanation:

Both statements are true: repetitive DNA occupies a large part of the human genome and generally has no direct protein-coding function. The lack of coding function does not, by itself, explain why these sequences are abundant.
