Presentation Transcript

  1. Cell cycle/cell division Bryan Tappen

  2. Interphase • Cell growth occurs • Chromatin is elongated and not visible • Distinct nucleus • DNA replication takes place • Cell appears to be resting http://faculty.ccbcmd.edu/courses/bio141/lecguide/unit6/genetics/DNA/DNArep/images/interphase1_pc.jpg http://emt.bu.edu/em610/em610_ol_spring_2008/yanti/interphase_text.JPG

  3. Prophase • Chromosomes become visible • Nuclear membrane breaks down • Centrioles and spindle fibers appear http://indi.blogs.com/indica/images/mitosis1Prophase.jpg http://www.cwinstead.com/prophase1.jpg

  4. Metaphase http://upload.wikimedia.org Chromosomes line up in the middle of the cell Spindle fibers attach to the centromere of the chromosomes http://media.smithsonianmag.com/images/HeLa-cells-metaphase-stage-2.jpg

  5. Anaphase • Duplicated chromosomes separate • Spindle fibers shorten pulling single chromosomes away from each other • Cytoplasm division begins www.uic.edu/classes/bios/bios100/lecturesf04am/anaphase1m.jpg http://morganterhune3a.edublogs.org/files/2011/11/anaphase-q9m62s.jpg

  6. Telophase Nuclear membrane starts to reform Chromosomes begin to uncoil and become less visible Cytoplasm division occurring http://www.broadinstitute.org/bbbc/BBBC018 http://www.edupic.net/cells.htm

  7. Cytokinesis • The division of the cytoplasm • Different in the plant and animal cells • Plant cells, cells reach cell wall • Animal cells, cells do no reach cell wall http://www.edupic.net/cells.htm http://www.sparknotes.com/biology/cellreproduction/mitosis/section3.rhtml
