    I asked myself this question for a long time , why must cells duplicate their DNA before cellular divison begins? Thanks for helping!

    Well, ask yourself this question. Would it be very helpful to duplicate the DNA after the cell division ended?

    It is the only way to ensure that both cells that arise after the duplication will have DNA.
