Final answer:
Eukaryotic chromosomes contain multiple sites where DNA replication can be initiated, and the process involves the formation of a prereplication complex at the origin of replication.
Step-by-step explanation:
Eukaryotic chromosomes contain many different sites where DNA replication can be initiated.
The replication of eukaryotic chromosomes involves the formation of a prereplication complex at the origin of replication. This complex recruits enzymes involved in the initiation of replication, such as helicase, topoisomerase, RNA primase, and DNA polymerase. Once replication is initiated, DNA polymerases facilitate the elongation process.
Overall, eukaryotic DNA replication is similar to that in prokaryotes, but it requires multiple replication forks compared to prokaryotic replication, which uses a single origin to rapidly replicate the entire genome.
