If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a eukaryote.
The helicase shown here, from PDB entry 4esv , separates DNA strands during the replication of a bacterial genome. The chromosome is a circle and replication begins at one point on the circle (called the origin) and proceeds in both directions, finishing on the opposite side.
