Document Summary
Cell division interesting facts: some cells don"t have nuclei. On the surface of the eye, there is a layer of epithelial cells that do contain a nucleus. There is an area of differentiation, which form lens fibers, which do. Lens fibers cannot divide: embryogenesis: requires cell division and differentiation (duh), loss of cell cycle regulation leads to cancer. 1,00,000,000 cells for this to occur: cell division has checkpoint systems, which is essentially a surveillance method to stop miscoding from occurring, cell division is balanced by apoptosis, ex. The cell cycle - discovered by howard and pelc in. G0: (cid:498)quiescent period. (cid:499) cells not actively engaged in cell cycle activity. A: synchronize cells in culture so they are undergoing the cell cycle at the same time. We can synchronize the cells so they stop at the g0 to g1 phase. At the same time, we will add 3h-thymidine, and then release them (allow them to resume the cycle).
