Okazaki fragments
DNA replication for the lagging strand is discontinuous and away from the replication fork. The small fragments synthesized are called Okazaki fragments and later stitched together by DNA Ligase.

Eventually, the last RNA attaches, and DNA polymerase and DNA ligase come along to convert the RNA (of the primers) to DNA, and seal the gaps in between the Okazaki fragments.

Pol III lengthens the bursts, forming Okazaki fragments. Pol I then "reads" the fragments, removes the RNA, and adds its own nucleotides (this is necessary because RNA and DNA use slightly different kinds of nucleotides).

A check on completion of S phase. The cell seems to monitor the presence of the Okazaki fragments on the lagging strand during DNA replication. The cell is not permitted to proceed in the cell cycle until these have disappeared.

Primase
An enzyme that synthesizes ribonucleotide primers for lagging strand DNA synthesis of Okazaki fragments. Polymerizes ribonucleotide triphosphates in the 5' to 3' direction.

Since the DNA strands are antiparallel, and replication proceeds in thje 5' to 3' direction on EACH strand, one strand will form a continuous copy, while the other will form a series of short Okazaki fragments.
