Final answer:
In double-stranded DNA, replication along the 5' → 3' template strand is discontinuous, involving short segments called Okazaki fragments, synthesized away from the replication fork.
Step-by-step explanation:
In double-stranded DNA, replication along the 5' → 3' template strand is discontinuous. This is because DNA polymerase can only add nucleotides in the 5' to 3' direction. The strand that is complementary to the 5' to 3' parental DNA strand must be extended away from the replication fork in small segments known as Okazaki fragments, each segment requiring a primer to initiate synthesis. These fragments are synthesized in a discontinuous manner, contrary to the leading strand which is synthesized continuously towards the replication fork.
