The elongation of the leading strand during DNA synthesis
A) progresses away from the replication fork.
B) occurs in the 3' → 5' direction.
C) produces Okazaki fragments.
D) depends on the action of DNA polymerase.
E) does not require a template strand.

Question

Quizplus · Accepted Answer

Elongation of the leading strand involves the action of DNA polymerase, which adds nucleotides in the 5' → 3' direction, towards the replication fork.

Note: A, B, and C are incorrect because elongation of the leading strand does not involve Okazaki fragments and progresses in the 5' → 3' direction towards the replication fork (not away from it). E is also incorrect because a template strand is required for DNA synthesis.
