Detailed explanation-1: -The similarities between prokaryotic and eukaryotic replication can be understood as follows: Both the replication processes occur before nuclear division. The DNA involved in both processes are double-stranded. The replication occurs in 5’ to 3’ direction.
Detailed explanation-2: -In prokaryotes, DNA replication is the first step of cell division, which is primarily through binary fission or budding. In eukaryotes, cell division is a comparatively complex process, and DNA replication occurs during the synthesis (S) phase of the cell cycle.
Detailed explanation-3: -In prokaryotes, DNA polymerase III is the main enzyme responsible for replication. DNA polymerase I and II have a role to play in repair, removing the primer and filling the gaps. In eukaryotes, DNA polymerase is the main enzyme for replication.
Detailed explanation-4: -Which is one way that DNA replication is similar in eukaryotic cells & prokaryotic cells? DNA is considered this because each new DNA molecule is made up of one original and one new strand: The two original strands are replicated in opposite directions.
