Eukaryotic Replication's Multiple Origins and Polymerases

Video not yet published

State

A eukaryotic chromosome replicates from many origins at once, and uses several distinct DNA polymerases rather than the few found in prokaryotes.

Show

A single human chromosome opens hundreds of replication bubbles simultaneously, each with its own forks, finishing far faster than one origin could.

Watch for

Multiple origins solve a length problem, not a fidelity problem — proofreading is what keeps eukaryotic replication accurate.
