The correct answer is: B) Prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many.
The difference between prokaryotic and eukaryotic replication is due their complexity difference. Prokaryotic cell has no nucleus (replication takes place in the cell cytoplasm), or other organelles. Also, eukaryotic cell has much more DNA than a prokaryotic cell.
Difference in replication:
• Origin- In prokaryotes there is only one point of origin, and replication occurs in two opposing directions at the same time (eukaryotes have multiple points of origin and unidirectional replication)
• Enzyme polymerase-prokaryotes have two types of them, while eukaryotes have four
• Speed rate- faster rate in prokaryotic cells and happens continuously
• Telomeres-eukaryotic cells have them.
