Document Summary
Bio lecture notes - cell cycle and mitosis. The vast majority of cells in the adult body are not dividing. Two major problems to solve in cell division: the actual feat of cell division. Both new cells need to have everything that the original cell had: only getting cell division when and where it is beneficial to the organisms regulation. If an adult human being loses an arm in an accident, it does not re-grow. Developmental processes for growing limbs are not reactivated when a limb is lost later in life. Cell cycle = from the time a cell is formed (from the division of its parent cell), to the time it undergoes its own division into two cells. All of the dna in the cell is being duplicated. ** some cells (neurons) will ever go through this whole cycle. Cells can go from g1 to g0. Very few of our cells are in interphase at any one time.
