In human cells about 50 nucleotides are added every second to a new strand of DNA at that rate it would take days to to replicate a molecule of DNA. So it replicates all along the chromosome so it only takes a few hours.
The DNA only needs to replicate if the cell is going to divide. In a dividing cell the DNA must replicate in order to provide a complete copy of the genome to each new cell.
They need to duplicate themselves because when cell division occurs, a new set of DNA needs to be split into another cell.
It cannot replicate without DNA. All living things are made up of DNA.
so that there will be two sets of DNA ... one for each new cell. If the DNA doesnt replicate one new cell would have no DNA. and cells need DNA.
The S phase of the cell cycle
Cells do not replicate "In DNA". Cells replicate their DNA during the process of cell division.

In the cell nucleus
mitosis
DNA is the genetic "instructions" for how the cell should replicate. It also controls the behavior of the cell.
to produce another copy of the cell you're trying to replicate
its how you can replicate the DNA and make the 5 steps ;)
because the DNA cannot leave the nucleaus. so it creates a duplicate of the DNA so the process of mitosis can carry out
cells must copy their DNA to replicate
A virus replicates its DNA in a cell when it infects the host
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
