WebSo, DNA replication in eukaryotes is ~10x slower and the individual DNA molecules are usually much larger, but replication takes place from multiple sites. Some examples: The bacteria Escherichia coli (often abbreviated … WebJul 6, 2024 · Let's say we have two DNA molecules of equal length, one belonging to a prokaryote and the other to an eukaryote. It's known that replication of the eukaryotic DNA is faster in this case. One clear reason for this is that linear DNA has multiple origins of replication whereas circular DNA only has one.

The mechanism of DNA replication primer synthesis by RNA pol

WebThe answer lies in a previously unknown transcription elongation complex that may also link DNA replication and transcription machineries.
