4) Describe in detail how p53 and MDM2 regulate cell division in a normal, healthy cell. You should describe 1) how these proteins cooperate to allow a cell to go through the cell cycle, 2) how they cooperate to stop the cell cycle, and 3) how they allow the cell cycle to continue again after having stopped it initially. You may use point form if you want.
