  1. what is mitosis
    • distributes identical chromosomes (DNA) molecules to each new cell formed when original cell divides
    • allows cells to reproduce
    • makes heredity possible
  2. stages of mitosis
    • IPMAT
    • or
    • PMATI
  3. prophase
    • chromatin granules become organized
    • c/s (pairs of lined c/m) appear
    • centrioles move away from nucleus
    • nuclear envelope disappears, freeing genetic material
    • spindle fibers appear
  4. metaphase
    • c/s align across center of cell
    • spindle fibers attach to each c/m
  5. anaphase
    • centromeres break apart
    • seperated c/m are called c/s
    • c/s pulled to opposite poles of cells
    • cleavage furrow
  6. telophase
    • cell division completed
    • nuclei appear in daughter cells
    • cytoplasm divides (cytokinesis)
    • daughter cells become fully functional
