You slough off all your skin cells once every seven years. Thank goodness for mitosis, or we would all be looking pretty strange without skin. The video begins by reviewing the cell cycle, looks at an overview of cells undergoing mitosis, analyzes the role of the cell membrane and nuclear membrane in mitosis, and watches the centrosomes actions throughout mitosis. Learners see how chromosomes change throughout the process and before exploring each phase.
