  3. What is MITOSIS ? THE PROCESS BY WHICH TWO NEW NUCLEII ARE FORMED, PRECEDING CELL DIVISION. http://fairmanstudios.com/als.htm

  4. PURPOSE OF MITOSIS: TO PRODUCE TWO NEW NUCLEII WITH… • EXACTLY THE SAME KIND and - EXACTLY THE SAME NUMBER . . . OF CHROMOSOMES AS THE PARENT CELL.

  5. http://www.dartmouth.edu/artsci/bio/cbbc/courses/bio4/bio4-lectures/theCell.htmlhttp://www.dartmouth.edu/artsci/bio/cbbc/courses/bio4/bio4-lectures/theCell.html 1 2 CYTOKINESIS MITOSIS is about organizing and distributing CHROMOSOMES

  6. INTERPHASE http://iccbweb.med.harvard.edu/mitchisonlab/Pages/mt.html

  7. interphase interphase

  8. INTERPHASE is the normal lifetime of a cell, after being “born” by division, and before it divides itself. MITOSIS INTERPHASE is not a stage of mitosis ! Biological Science, a Molecular Approach. BSCS Blue Version. Heath and Company, 1996.

  9. INTERPHASE: Gap 1 MITOSIS Gap 2 S-phase Biological Science, a Molecular Approach. BSCS Blue Version. Heath and Company, 1996.

  10. nucleolus (if any) still visible INTERPHASE: nuclear envelope clearly visible chromatin, NO chromosomes, yet http://www.fed.cuhk.edu.hk/~johnson/photomicrographs/mitosis/animal/animal_interphase.htm

  11. INTERPHASE Allium root tip Coregonus blastula

  12. PROPHASE http://www.itg.uiuc.edu/technology/atlas/structures/mitosis/prophase.htm

  13. PROPHASE J Nuclear membrane dissolves. J Nucleolus disappears. J Chromosomes form. J Centrioles migrate & form spindle. http://www.blc.arizona.edu/courses/181gh/Lectures_WJG.01/mitosis_F.01/mitosis.html

  14. PROPHASE nuclear envelope disappears nucleolus disappears chromosomes become visible http://www.ac-dijon.fr/pedago/svt/documents/mitose/prophase.gif

  15. PROPHASE Allium root tip Coregonus blastula

  16. METAPHASE http://iccbweb.med.harvard.edu/mitchisonlab/Pages/mt.html

  17. METAPHASE chromatids spindle centriole http://www.chembio.uoguelph.ca/educmat/chm736/cycletx.htm J chromatids line up on the equator.

  18. METAPHASE TWO IDENTICAL COPIES OF ONE CHROMOSOME. THIS CHROMATID WILL SOON MOVE TO NORTH POLE THIS CHROMATID WILL SOON MOVE TO SOUTH POLE http://genenlab.spoono.com/gnu/mandm.shtml

  19. chromatids spindle centriole Nature (408. 423, 2000). http://www.blc.arizona.edu/courses/181gh/Lectures_WJG.01/mitosis_F.01/mitosis.html

  20. METAPHASE Allium root tip Coregonus blastula

  21. ANAPHASE http://www.univ-orleans.fr/SCIENCES/BIOCHIMIE/MMC/accueil.htm

  22. ANAPHASE J chromatids migrate to each pole. http://www.blc.arizona.edu/courses/181gh/Lectures_WJG.01/mitosis_F.01/mitosis.html

  23. ANAPHASE early late Conly Rieder http://www.wadsworth.org/BMS/SCBlinks/WEB_MIT2/HOME.HTM

  24. ANAPHASE Allium root tip Coregonus blastula

  25. TELOPHASE

  26. TELOPHASE http://www.bmb.psu.edu/courses/bisci2/mitosis/mitosis.htm J Chromosomes dissolve. J Mitotic spindle dissolves. J Nuclear membrane forms. J New nucleoli form.

  27. TELOPHASE ONE DAUGHTER NUCLEUS FORMS AT NORTH POLE ONE DAUGHTER NUCLEUS FORMS AT SOUTH POLE SPINDLE APPARATUS DISSOLVES

  28. TELOPHASE early late New nuclei form at the poles. Cytokinesis begins. http://www.blc.arizona.edu/courses/181gh/Lectures_WJG.01/mitosis_F.01/mitosis.html

  29. TELOPHASE Allium root tip Coregonus blastula
