Document Summary
At top we can see mitotic microtubule assembly, and will then divide equally. Bottom oriented differently; when those four cells divide, they will give rise to smaller daughter cells (micrometers) due to asymmetric cell division. M phase: usually takes up small portion of cell cycle, observed this because when cells in culture together, very few were actually dividing at any given time. Cells that do not divide are in g0. Ensures that cells go through this cycle that they"re supposed to go through. Problems with this control system may lead to chromosome segregation defects (ending up with two daughter nuclei without the correct amount of chromosomes) or cancer cells (uncontrolled growth) There are a group of proteins that control _____ ______ - kinases; dependent upon cyclins. M cyclin-dependent kinase drives entry of ____ for mitosis when all conditions are met.
