Biology - Cell Division

Why do scientists study cell division? What can they learn from it?
Well, how diseases can affect the rate of tissue growth and repair. How different tissues within the body rebuild themselves and also if it's possible to grow tissues and organs in case of transplant. :3
Could it be, amongst other things, to study genetics? I know that the only time when you can see the chromosomes is when the cell is preparing to divide as the nuclear envelope has broken down, and the chromosomes have supercoiled and can take up a stain. I'd imagine they'd study this to see what problems incorrect duplication of the chromosomes leads to, and whether this causes disease or not. That's just what I remember from AS biology so I think it's right :smile:
