  1. www.hbio3gbs1011.blogspot.com/2010/10/mitosis-10810.html Cell Division 3 stages of Cell Division: 1.}Interphase 2.}Mitosis 3.}Cytokinesis

  2. Interphase (Prep. Stage) • Grow • DNA replicates {copy} • Prepares to divide • 90% chromatin http://www.haverford.edu/biology/Johnson/ http://www.ous-research.no/home/lothe/methods/1389 http://www.rci.rutgers.edu/~uzwiak/GBSummer12/GB101Summer12Lect/GB101Summer_Lect14.htm

  3. Mitosis(division of nucleus) • Prophase • Metaphase • Anaphase • Telophase http://www.google.com/imgres?q=prophase+metaphase+anaphase+telophase&hl=en&safe=active&biw=1280&bih=929&tbm=isch&tbnid=pFF6nQN10WgN0M:&imgrefurl=https://dbscience2.wikispaces.com/Sara&docid=3ZnaS98omXhAgM&imgurl=https://dbscience2.wikispaces.com/file/view/saraskippmitosis.gif/62793330/saraskippmitosis.gif&w=450&h=538&ei=0rdcUOr7JKLv0gHbl4GAAw&zoom=1&iact=hc&vpx=378&vpy=121&dur=1926&hovh=246&hovw=205&tx=140&ty=148&sig=117498511410069916228&page=1&tbnh=133&tbnw=111&start=0&ndsp=32&ved=1t:429,r:1,s:0,i:73 Nucleus membrane & nucleus disappear Spindle fibers appear Duplicated chromosomes

  4. Prophase • Nucleus membrane & nucleus • Spindle fibers appear • You can see duplicated chromosomes http://www.smithsonianmag.com/specialsections/women-in-science/115193624.html http://www.chescientific.com/edu/product_115.aspx

  5. Metaphase • Duplicated chromosomes move to the middle • Sister chromatids separate & move to opposite ends http://www.fcgov.com/lctix/galleries-exhibitions.php http://www.yvonnebraden.com/Mitosis%20Flip%20Book%20Warm-up.htm

  6. Anaphase • Sister chromatids separate & move to the opposite ends Fig. 1 blog.makezine.com http://www.conceptart.org/forums/showthread.php?t=165902

  7. Telophase http://iboss.com/cb/charlotte/restricted.html?fn=students&fp=2&ip=10.11.43.56&ibip=10.11.11.48&ldu=0&re=1&bu=queinteresante2010.blogspot.com/2011/04/prophase-metaphase-anaphase-and.html&bc=Website%20contains%20prohibited%20Private%20Websites%20content. • Nuclear membrane & nucleus reappear • Chromosomes loosen up & become chromatin http://student.ccbcmd.edu/~gkaiser/biotutorials/dna/mitosis/actelophase.html

  8. Cytokinesis • Division of {cytoplasm} • Always moving to the next stage http://search.wn.com/?pagenum=7&results_type=videos&language_id=1&search_type=expression&search_string=cytokinesis&sort_type=-pub-datetime&template=cheetah-search-adv%2Findex.txt&action=search&corpus=current http://www.sparknotes.com/biology/cellreproduction/mitosis/section3.rhtml
