What is one difference between DNA replication in bacteria versus eukaryotes?
Added by James D.
Step 1
In bacteria, DNA replication occurs in the cytoplasm since they lack a defined nucleus. In eukaryotes, DNA replication occurs in the nucleus, where the DNA is housed. Show more…

DNA replication in eukaryotes differs from replication in bacteria because: - DNA replication is bidirectional in eukaryotes and unidirectional in bacteria. - Synthesis of the new DNA strand is from 5' to 3' in eukaryotes and from 3' to 5' in bacteria. - Okazaki fragments are produced in eukaryotic DNA replication but not in prokaryotic DNA replication. - The eukaryotic DNA replicons are linear, which creates a problem for the replication of the edges of the lagging strands, whereas the circular bacterial chromosomes do not have such a challenge. - There are many replication origins in the single bacterial chromosome and only one in each chromosome of eukaryotic cells.

Why is DNA replication different between eukaryotes and prokaryotes? Because it involves genomes of different sizes Because replication in prokaryotes only involves the leading strand Because Okazaki fragments are specific to eukaryotes Because in one case replication is bi-directional, in the other it's uni-directional A big difference between bacterial and eukaryotic cell DNA replication involves (select the best answer below) the presence or absence of a leading and lagging strand the presence or absence of Okazaki fragments the size of the genome that needs to be replicated initiating replication in a uni-directional manner the presence or absence of the helicase enzyme
