Question

Given below are two statements, one is labelled as Assertion (A) and other labelled as Reason (R).
• [Assertion (A):] During DNA replication, the lagging strand is replicated in short pieces. 
• [Reason (R):] DNA polymerase can synthesize the DNA only in one direction i.e. 5' to 3'. 
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:

Remember:
- Leading strand: Synthesized continuously toward the replication fork.
- Lagging strand: Synthesized discontinuously as Okazaki fragments away from the replication fork.
This asymmetry is caused by the 5' to 3' directional limitation of DNA polymerase.

Answer 1

The Correct Option is A
