PPT-Mitosis-Cell Division Stages Of Mitosis

Interphase The in between stage Originally metaphase was thought to be a resting stage now we know that this is the stage most cells spend their time in doing the things that cells do and if they are preparing to divide growing and replicating their DNA.
