multiple initiation sites for eukaryotic replication

Post by Tiamaria » Fri Feb 18, 2011 7:58 pm

Hello everyone,
I'm stuck on a question and i was hoping you could offer some assistance.
I've figured out half the question (i think) but i'm not sure on one more reason.

Question:
What are the two major reasons for the multiple initiation sites for eukaryotic replication?

Answer:
1- so that synthesis can take place rapidly and at multiple sites. Rather than simply synthesizing one protein, it can synthesis many at one time.

2- i have no idea.

If you can help me or guide me or tell me where to browse that would be great. Thanks everyone!!

if you're asking for replication, then you're not refering to protein synthesis ;)

Cis or trans? That's what matters.

1. As you wanted to mean in your first answer, it makes things go faster. Since eukaryotic genomes are bigger than prokaryotic genomes, there are multiple initiation sites for replication. But, prokaryotes have one.

2. I think the other reason is that an eukaryot has multiple chromosomes and every each of them have to have at least one initiation site for replication. But, a bacterium (a prokaryote) have one circular chromosome and only one initiation site is enough for replication.
