It all begins from mitosis. Mitosis is the process of the cell division. Mitosis starts when the chromatin within the cell begins to rearrange into orderly strand called chromosomes. The chromosomes then move into pairs. After that, the chromosome pairs begin to pull apart from each other. Eventually, the chromosome pairs split apart into two new cells with the same makeupas the original cell.
