Question

Answer

Multiple Origins of Replication in Eukaryotes
Prokaryotic DNA replication differs from eukaryotic DNA replication in terms of the number of origins of replication. In prokaryotes, there is typically only one origin of replication where the replication process initiates. On the other hand, eukaryotic cells have multiple origins of replication scattered throughout their genome. This allows eukaryotic cells to replicate their DNA faster and more efficiently compared to prokaryotic cells.

Explanation:
- Prokaryotic DNA replication starts at a single origin of replication, known as the oriC region.
- Eukaryotic DNA replication begins at multiple origins of replication, which helps in accelerating the replication process.
- The presence of multiple origins of replication in eukaryotes allows for greater replication efficiency and faster DNA synthesis.

Conclusion:
The presence of multiple origins of replication in eukaryotes is a key difference that distinguishes eukaryotic DNA replication from prokaryotic DNA replication. This difference contributes to the higher replication rate and efficiency observed in eukaryotic cells compared to prokaryotic cells.
