  1. 1. Nucleus  with a nuclear envelope and Chromatin inside<br />Do you remember what chromatin is?<br />chro·ma·tin  (krō’-ma-ten) n. A complex of nucleic acids and proteins, primarily histones, in the cell nucleus that stains readily with basic dyes and condenses to form chromosomes during cell division.<br />A cell with four chromosomes<br />
  2. 2. During Prophase, the nuclear envelope breaks down and a spindle forms between two centrioles.<br />Example:<br />
  3. 3. Metaphase  Chromosomes are now doubled and are aligned at middle of cell, chromosome are attached to centrioles by spindle fibers.<br />
  4. 4. Metaphase  Chromosomes are now doubled and are aligned at middle of cell, chromosome are attached to centrioles by spindle fibers.<br />
  5. 5. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.<br />
  6. 6. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.<br />
  7. 7. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.<br />
  8. 8. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.<br />
  9. 9. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.<br />
  10. 10. Anaphase  Chromosomes pairs begin to pull apart to opposite ends.<br />
  11. 11. Telophase Spindle fibers disappear, cell starts to devide.<br />

  14. 14. Telophase Spindle fibers disappear, cell starts to devide.<br />
  15. 15. Telophase Spindle fibers disappear, cell starts to devide.<br />
  16. 16. Telophase Spindle fibers disappear, cell starts to devide.<br />

  24. 24. Telophase Spindle fibers disappear, cell starts to devide.<br />
  25. 25. Telophase Spindle fibers disappear, cell starts to devide.<br />
  26. 26. Telophase Spindle fibers disappear, cell starts to devide.<br />
  27. 27. Telophase Spindle fibers disappear, cell starts to devide.<br />
  28. 28. Telophase Spindle fibers disappear, cell starts to devide.<br />

  30. 30. Telophase Spindle fibers disappear, cell starts to devide.<br />
  31. 31. Telophase Nuclear membrane begins to form.<br />
  32. 32. Cytokinesis Two daughter cells are formed.<br />
  33. 33. Cytokinesis Two daughter cells are formed.<br />
