  • A mnemonic to help remember the stages of mitosis.
  • Mitosis ppt

    1. 1. How do little elephants grow up to be BIG elephants?
    2. 2. M: mitosis (Cell divides) G2: Cell doublechecks to make sure DNA is replicated and cell has enough organelles for the upcoming split G1: Cell grows in size. S: Cell makes identical copy of its DNA
    3. 3.      What are the three phases of Interphase? What happens during S phase? What happens during G1 phase? What happens during M phase? What happens during G2 phase?
    4. 4. Animated Mitosis Cycle http://www.cellsalive.com/mitosis.htm • Interphase • Prophase • Metaphase • Anaphase • Telophase & Cytokinesis http://highered.mcgraw-hill.com/olcweb/cgi/pluginpop.cgi?
    5. 5. • • Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils (chromatin) at the start, but the DNA and its copy change to sister chromatids at end of this phase

    7. 7. • • • • Nucleus starts to disappear. Chromatin coils to become chromosomes. Centrioles (or poles) appear and begin to move to opposite end of the cell. Spindle fibers form between the poles.

    9. 9. • Chromatids (a pair of identical chromosomes) are dragged to middle of cell along the metaphase plate.
    10. 10. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
    11. 11. • Chromatids (or pairs of identical chromosomes) separate and begin to move to opposite ends of the cell. Sister chromatids
    12. 12. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
    13. 13. • • • Two new nuclei form. Chromosomes unwind into chromatin (threads rather than rods). Mitosis ends.

    15. 15. • Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes.
