Replication Forks
DNA synthesis occurs at numerous different locations on the same DNA molecule (hundreds in a human chromosome).
These form bubbles of replication with a replication fork at the growing edge.

Replication fork The site of DNA synthesis where the parental strands are separated and daughter strands complementary to each parent are synthesized.

Problem 4: The replication fork
In this diagram of the process of DNA replication at a replication fork, the newly synthesized DNA strand labeled C is the:
A coding strand
B parental DNA ...

Eukaryotic DNA has many replication forks and also bidirectional synthesis, contrasting to the unidirectional rolling theta prokaryotic method.

Then, as the replication fork nears the end of the DNA, there is no longer enough template to continue forming Okazaki fragments. So the 5' end of each newly-synthesized strand cannot be completed.

In DNA replication, the lagging strand is the DNA strand at the opposite side of the replication fork from the leading strand. It goes from 5' to 3' (these numbers indicate the position of the molecule in respect to the carbon atoms it contains).
