Final answer:
Item sorting for DNA replication features shows that linear chromosomes with multiple origins and the need for nucleosome removal are features unique to eukaryotic replication, while a circular chromosome with one origin is specific to bacterial replication. Common features between both include bidirectional synthesis, a requirement for primers, and the formation of replication forks. Eukaryotic replication involves numerous DNA polymerases, including some found in mitochondria.
Step-by-step explanation:
The general mechanism of DNA replication involves a similar fundamental process in both bacteria and eukaryotes, although there are some key differences which make the eukaryotic replication more complex. For instance, eukaryotic DNA is packaged into nucleosomes and chromatin structure has to be altered to make DNA accessible; there are multiple origins of replication on linear chromosomes; and a greater number of DNA polymerases are involved in the process. Let's sort the items as per their occurrence in bacterial or eukaryotic replication or in both:
- five polymerases including DNA Pol III holoenzyme - c. Both bacterial and eukaryotic replication
- bidirectional synthesis creates leading and lagging strands - c. Both bacterial and eukaryotic replication
- double-stranded DNA unwound at origin - c. Both bacterial and eukaryotic replication
- linear chromosomes with multiple origins - b. Eukaryotic replication
- replication forks formed - c. Both bacterial and eukaryotic replication
- nucleosomes must be removed - b. Eukaryotic replication
- circular chromosome with one origin - a. Bacterial replication
- polymerases need a primer - c. Both bacterial and eukaryotic replication
- numerous polymerases including Pol α, β, σ, and γ found in mitochondria - b. Eukaryotic replication
