Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : DNA replication is a semi-conservative process.
Reason (R) : In semi-conservative DNA replication, the two strands of DNA are separated, and each strand serves as a template for the synthesis of a new complementary strand. Therefore, each new double-stranded DNA molecule consists of one original strand and one newly synthesized strand.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

To test if the Reason explains the Assertion, read them together using the connector "because":
"DNA replication is semi-conservative BECAUSE when the two strands separate, each serves as a template to make a new complementary strand, resulting in new DNA molecules with one original and one new strand."
This reads as a logical, scientifically correct explanation.

Answer 1

The Correct Option is A
