Because mitosis needs new DNA to continue
If you think about the order mitoses goes throw it makes more since.
the DNA replicates before mitosis begins
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
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
no DNA replicates before mitosis. It replicates in the S phase of inter phase

No, transcription is the process of creating an mRNA copy of the DNA in order to create a function process (by translation at the ribosomes). However, DNA does replicate before mitosis occurs - this is so that each daughter cell at the end of mitosis ends up with the same number of chromosomes as the original cell.
because the DNA cannot leave the nucleaus. so it creates a duplicate of the DNA so the process of mitosis can carry out
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.
