Directions: In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as:
Assertion: Synthesis of daughter or new strand occurs continuously along the parent 3' → 5' strand.
Reason: DNA polymerase can polymerise nucleotides in 3' → 5' direction on 5' → 3' strand.
Reason: DNA polymerase can polymerise nucleotides in 3' → 5' direction on 5' → 3' strand.
- a)If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
- b)If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
- c)If Assertion is true but Reason is false.
- d)If both Assertion and Reason are false.
Correct answer is option 'C'. Can you explain this answer?

DNA-polymerase can polymerise nucleotides only in 5' → 3' direction on 3' → 5' strand because it adds them at the 3' direction on 3' → 5' strand because it adds them at the 3' end. Replication over the two templates proceeds in opposite directions. One strand with polarity 3' → 5' forms its complementary strand continuously because 3' end of latter is always open for elongation. It is called leading strand. Replication is discontinuous on the other template with polarity 5'→ 3' because only a short segment of DNA strand can be built in 5' → 3' direction due to exposure of a small stretch of template at one time. Short segments of replicated DNA are called Okazaki fragments. DNA strand built up of Okazaki fragments is called lagging strand. As one strand grows continuously while the other strand is formed discontinuously, DNA replication is semidiscontinuous.

Understanding the Assertion and Reason
The assertion states that the synthesis of the daughter or new strand occurs continuously along the parent 3' → 5' strand. The reason provided is that DNA polymerase can polymerize nucleotides in the 3' → 5' direction on the 5' → 3' strand.
Analysis of the Assertion
- True Statement: The assertion is true because during DNA replication, the new strand is synthesized continuously on the parent strand that runs in the 3' to 5' direction.
- Leading Strand: This is referred to as the leading strand, which is synthesized continuously.
Analysis of the Reason
- False Statement: The reason is false. DNA polymerase can only add nucleotides in the 5' → 3' direction, which means it cannot polymerize nucleotides in the 3' → 5' direction.
- Direction of Synthesis: Therefore, it synthesizes new strands in the 5' → 3' direction, not the other way around.
Conclusion
- Since the assertion is true and the reason is false, the correct answer is option 'C': Assertion is true but Reason is false.
This distinction is crucial in understanding the mechanics of DNA replication, particularly how the leading and lagging strands are synthesized.
