Introduction To Mitosis

  1. 1. Introduction To Mitosis AP Biology
  2. 2. Phases of Mitosis <ul><li>Interphase- Not part of Mitosis but the much longer phase before the cell splits. </li></ul><ul><li>Prophase- Spindles formed by microtubules. </li></ul><ul><li>Metaphase- Centromeres convene along metaphase plate. </li></ul><ul><li>Anaphase- Sister Chromatid split and move to opposite sides of the cell. </li></ul><ul><li>Telophase- New nuclear envelope is formed using parts of the parent cells nuclear membrane. </li></ul>
  3. 3. Interphase
  4. 4. Interphase <ul><li>Cell prepares for division. </li></ul><ul><li>Three stages: </li></ul><ul><li>G1- Cell Grows. </li></ul><ul><li>S- Chromosomes replicated. </li></ul><ul><li>G2- Cell grows and prepares for division. </li></ul>
  5. 5. Prophase
  6. 6. Prophase <ul><li>In plant cells only prophase is preceded by Preprophase. </li></ul><ul><li>Chromatin condenses into chromosomes. </li></ul><ul><li>Spindles begin for form. </li></ul><ul><li>Motor proteins push Centrosomes along microtubules to opposite ends of the cell. </li></ul>
  7. 7. Metaphase
  8. 8. Metaphase <ul><li>Spindles attach to Centromeres and chromosomes convene along Metaphase plate. </li></ul><ul><li>Analogous to a Tug of War between people of equal strength. </li></ul>
  9. 9. Anaphase
  10. 10. Anaphase <ul><li>Proteins that bind sister Chromatid are split. </li></ul><ul><li>Sister chromosomes are pulled apart by shortening spindles and move towards their respective centrosomes. </li></ul>
  11. 11. Telophase
  12. 12. Telophase <ul><li>New nuclear envelope formed from parts of the parent cells nuclear membrane. </li></ul><ul><li>Chromosomes are enveloped in new nuclei and are unpacked into chromatin. </li></ul><ul><li>Mitosis is now complete. </li></ul>
