Which of the following are true about bacterial DNA replication compared to DNA replication in ...

Correct Answers:

Bacteria can replicate their entire genome more quickly than human cells can

Bacteria can replicate their DNA continuously but eukaryotes can wait for the S phase of the cell cycle.

Explanation

Since prokaryotic or bacterial cells typically have only a single, circular chromosome, they can replicate faster than eukaryotic cells which have larger linear dna arranged in chromosomes.

There is no mitosis in bacteria and thus no cell cycle so DNA replication is not restricted to S phase as in eukaryotes.

Explanation for wrong answers

Bacteria DNA replication uses only one type of DNA polymerase

Helicase enzyme is the enzyme which is required to separate the two double stranded DNA whether in bacteria or eukaryotes. The DNA is always double stranded in both, hence helicase is needed, to separate out both the strands so that DNA polymerase could bind to both the strands starting the replication process.

Origin is the location of start of DNA replication in both eukaryotes and prokaryotes. In both of them,  origin usually consists of AT sequences as adenine and thymine are bonded to each other by only two hydrogen bonds, as a result, these sequences are easy to break down  and they comprise of origin so that the two hydrogen bonds may be easily broken down and both the strands open from this specific location, making the origin the best start point of DNA replication.

Because of the huge DNA eukaryotes gave  multiple origins in comparison to bacteria which have single origin.
