|
Prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many.
|
|
|
Prokaryotic chromosomes have histones, whereas eukaryotic chromosomes do not.
|
|
|
The rate of elongation during DNA replication is slower in prokaryotes than in eukaryotes.
|
|
|
Prokaryotes produce Okazaki fragments during DNA replication, but eukaryotes do not.

Detailed explanation-1: -This is because eukaryotic chromosomes are much larger, so multiple origins are needed to replicate the entire chromosome in a short amount of time. Prokaryotic chromosomes are small, so they can get away with having only one origin.
Detailed explanation-2: -Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.
Detailed explanation-3: -Answer and Explanation: One key difference between the process of DNA replication in eukaryotes and prokaryotes is that eukaryotic cells have multiple origins, while prokaryotes have just one.
Detailed explanation-4: -1 Answer. The differences between DNA replication in prokaryotic and eukaryotic cells is due to the location, complexity, and size of the cell.
Detailed explanation-5: -While prokaryotic genomes only have one origin of replication, multiple origins are present simultaneously in the eukaryotic genome to allow for faster replication. Origin of replication: A particular sequence in a genome at which replication is initiated. DNA replication: The process by which DNA is copied.
