Assertion: If each strand from a DNA acts as a template for the synthesis of a new strand, the two double stranded DNA thus, produced would be identical to the parental DNA molecule.
Reason: The two strands in a double stranded DNA molecule are identical to each other and antiparallel.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
