because the DNA cannot leave the nucleaus. so it creates a duplicate of the DNA so the process of mitosis can carry out
mitosis
Cells replicate for many reasons, they replicate by a process of mitosis or meiosis. Mitosis producing two daughter cells and meiosis producing gamete cells (sperm or ovum(egg) )
the DNA replicates before mitosis begins
DNA must replicate before mitosis can begin. Mitosis is another word for cell division and so there needs to be two copies of the DNA for the two new cells.

mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process

Cells do not replicate "In DNA". Cells replicate their DNA during the process of cell division.
no DNA replicates before mitosis. It replicates in the S phase of inter phase
The DNA replicates before mitosis begins
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
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.
No. Chromosomes have the exact number of DNA a cell needs. When undergoing mitosis, the chromosomes replicate inside the cell. Only during that small period of time, does a normal human cell have twice the DNA that a cell needs. The end stage of mitosis is when the cell divides into two, equally dividing the DNA amongst the two daughter cells.
