The eukaryotic genome is so much larger than the prokaryotic genome that it would not be practical to rely on a single origin of replication site when copying it for cell division. By incorporating several, the eukaryotic cell can divide without unnecessarily long delay in chromosomal replication.

There are many theories to explain why genomic DNA in eukaryotes is condensed into several chromosomes. The most generally accepted theory suggests that many smaller chromosomes are easier to access during protein production and easier to copy for cell division than a single, massive and unwieldy chromosome.

Replication proceeds in both directions, creating replicating "bubbles". Hundreds or thousands of these bubbles can be created at once, shortening the time needed for replication.
