Why does genetic information need to be copied from the DNA?
Genetic information needs to be copied from DNA especially during Cell division, or mitosis. In mitosis a cell copies it's original chromosomes and the result is 2 sister chromatids. Once the cell splits the new cell has that copied chromosome, or 2 sister chromatids, and is know free to break down the chromosomes into chromatin, instead of it's original, coiled chromosome.

How do cell prepare itself before dividing?
Well first the chromosomes are copied (after the chromosomes are copied they are called chromatids), then the nuclear membrane disolves and the chromosomes become rodlike structures. 2nd the chromosomes line up in the middle of the cell.3rd The chromatids separate and move to opposite sides of the cell. All of those are basically what a cell does to prepare itself before it seperates.
