Four copies of a DNA molecule result from two replications of a single DNA molecule. This is because each replication results in two identical daughter molecules.

we started with a single strand DNA molecule.
Yes it is. The eukaryotic DNA polymerase works much slower than the prokaryotic DNA polymerase, working at around 50 bases per second. With as many as 80 million bases to replicate the job is achieved in about one hour by having many replication forks. The simple answer: It's quicker.

•single-copy replication control -A control system in which there is only one copy of a replicon per unit bacterium. -The bacterial chromosome and some plasmids have this type of regulation. •multicopy replication control -Occurs when the control system allows the plasmid to exist in more than one copy per individual bacterial cell.
