Compare and contrast DNA synthesis in prokaryotes and eukaryotes. What will be an ideal response?
The process of DNA replication in prokaryotes and eukaryotes is basically similar. The principal
differences result from differences in the structure and size of the prokaryotic and eukaryotic
chromosomes. Prokaryotic chromosomes are circular and relatively small; consequently there is only
one origin of replication (and two replication forks). Eukaryotic chromosomes are linear and relatively
long; consequently there are multiple origins of replication and multiple replication forks.
