Final answer:
The bacterial cell has one replicase for DNA replication, with many subunits, but several repair DNA polymerases, each with one or just a few subunits.
Step-by-step explanation:
While eukaryotic cells have multiple origins of replication to handle their larger DNA quantity, prokaryotic organisms like bacteria have a single origin of replication. However, there are several repair DNA polymerases. In E. coli, for example, the entire genome is replicated starting from this single point and proceeds bidirectionally, which allows for very rapid division — about 1000 nucleotides are added per second.
In contrast to prokaryotes, which primarily use DNA polymerase III for replication, eukaryotes have a wider range of DNA polymerases. Eukaryotes use at least fourteen different DNA polymerases, with five playing major roles during replication: pol α, pol β, pol γ, pol δ, and pol ε. This expansive array aids in managing the complex and voluminous eukaryotic genomes during replication and repair processes.
