What does the replication fork do in DNA replication?
Replication forks hold the two separated strands of DNA apart preventing them from assuming their double helic shape.
What sites separate and replicate in DNA?
replication forks separate and replicate DNA
Is it true formation of multiple replication forks tends to slow down DNA replication?
No, the whole point in forming multiple replication forks is to reduce the time it takes to replicated DNA by replicating several sections of DNA at the same time, so that each polymerase enzyme has to copy less of the DNA. As a result replication finishes earlier than it would if one polymerase were to replicate the entire strand (as it would operate at the same speed - about 1000 base pairs per second). The human genome has about 20,000 origins for replication, which will produce 20,000 replication forks. It is necessary to have this many because the human genome is so large (3.3 billion base pairs). Without 20,000 origins, DNA replication would take close to 20,000 times longer.
Which process does a DNA unzip?
to make a new copy before the cell splits
Is it true that Replication occurs simultaneously at many points on a DNA molecule?
Yes it is. The eukaryotic DNA polymerase works much slower than the prokaryotic DNA polymerase, working at around 50 bases per second. With as many as 80 million bases to replicate the job is achieved in about one hour by having many replication forks. The simple answer: It's quicker.
What is The action of helicase creates?
Replication Forks & Replication Bubbles
Do replication forks speed up replication?
Multiple replication forks working in concert, can be replicated in about 8 hours
Compare the number of replication forks in prokaryotic and eukaryotic DNA during replication?
Prokaryotic DNA is reproduced with DNA Polymerases replication forks.
During DNA replication why are there many replication forks?
because it just is
How does DNA replication differ in prokaryotes and eukaryotes?
1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete. In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
What does the replication fork do in DNA replication?
Replication forks hold the two separated strands of DNA apart preventing them from assuming their double helic shape.
Replication forks tend to?
two new strands of DNA jus guessing!!!
What sites separate and replicate in DNA?
replication forks separate and replicate DNA
Differentiate the number of replication forks in prokaryotic and eukaryotic DNA?

Do DNA have 1 or many replication forks?
Not sure, but good question! You may have to ask a doctor.
