I am sitting by Kelby L. ^ what kind of answer is that?
The advantage to having multiple sites of DNA replication is basically to quicken the process of DNA replication Why the process needs to be quicken... im not too sure...

How do eukaryotic organisms solve the problem of time constraints on replication of DNA?
The replication begins at origins along the DNA.
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
Does DNA replication start at only one place in the DNA?
What do you mean by one area? If by one area you mean does it start at one area then stop and continue on another area then no, DNA replication is continuous and when it takes place it is the most important thing going on in the cell. The cells resources are directed at this process * DNA replication means copying the entire DNA molecule, so it involves the entire molecule, but not all at the same time. In bacteria (prokaryotic cells) replication begins at one point in the molecule and continues all the way round the circular molecule.Beginning at just one place would take too long in eukaryotic cells; someone has calculated that our longest chromosomes would take about a fortnight to replicate, and we cannot wait that long! So replication begins at a number of sites along the length of the DNA molecule. At each replication site, as the DNA strands are separated there is a bulge in the molecule called a replication bubble. As replication proceeds these bubbles become longer, and eventually they merge into one another and the job is done.
Why replication of human chromosomes would takes so long with a single replication?
Replication of human chromosomes is a complex and time-consuming process because there are 46 chromosomes in each human cell, and each chromosome contains a large amount of DNA. Additionally, the replication process involves multiple steps and requires the coordination of many molecular machinery and enzymes. Furthermore, the DNA replication process must be highly accurate to prevent errors and maintain the integrity of the genetic material. All these factors contribute to the length of time required for replication.
What enzyme directs DNA replication?
the chains are first separated by enzymes called helicases.the helicase enzymes move along the DNA molecule and break the hydrogen bonds between the complementary bases separating the chains. then another enzyme called DNA polymerases comes and separates them even more creating new DNA molecules with new DNA and old DNA.
When DNA is copied the molecule splits open along the?
When DNA is copied, the molecule splits open along the double helix. This occurs during the process of DNA replication.
Replication explain how the structure of DNA allows it to be duplicated so easily why cant protein be copied so easily?
Replication begins when an enzyme called DNA helicase attaches to a DNA molecule, moves along the molecule, and "unzips" the two strands of DNA.

What are the 3 models of DNA replication?
Conservative replication would leave intact the original DNA molecule and generate a completely new molecule.Dispersive replication would produce two DNA molecules with sections of both old and new DNA interspersed along each strand.Semiconservative replication would produce molecules with both old and new DNA, but each molecule would be composed of one old strand and one new one.

What is the function of polyribosome?
Polyribosomes form along the same mRNA molecule, allowing for the formation of multiple copies of the protein being synthesized.

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 makes up the molecules at the end of DNA replication there are two identical DNA molecules?
During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these nucleotides are very particular about what they connect to. Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T). How the bases are arranged in the DNA is what determines the genetic code.
Where can one find an exchange replication service?
An exchange replication service may be purchased, along with other software, from Microsoft. It is software which has to do with mailboxes and other communicative applications.
