Understanding the Cell Cycle: Mitosis and Its Phases

This comprehensive overview delves into the cell cycle, focusing specifically on the process of mitosis. Mitosis consists of four key phases: prophase, metaphase, anaphase, and telophase, followed by cytokinesis, which concludes cell division. We explore each phase in detail, highlighting critical events such as the disintegration of the nuclear membrane, alignment of chromosomes, and the movement of sister chromatids. With extensive references and resources for further reading, this guide serves as an essential tool for understanding how cells replicate and divide efficiently.

  1. Cell cycle By: Devin mariannino

  2. Mitosis • Division of the nucleus • 4 phases http://www.wadsworth.org/BMS/SCBlinks/mcewen/dynamics.htm http://www.tokresource.org/tok_classes/biobiobio/biomenu/cell_division/index.htm

  3. Interphase • Grows • DNA replicates • Prepares to divide • 90% of the cells life http://micro.magnet.fsu.edu/cells/fluorescencemitosis/interphase2large.html http://blog.lib.umn.edu/michaels/thursmorn/2009/10/stages-of-mitosis.html

  4. Prophase • Nu clearmembrane despairs • Spindale fibers appear • You can see the duplicated chromosomes http://home.comcast.net/~llpellegrini/meiosis.html http://en.wikipedia.org/wiki/File:3D-SIM-3_Prophase_3_color.jpg

  5. Metaphase • http://www.yvonnebraden.com/Mitosis%20Flip%20Book%20Warm-up.htm http://www.wellcome.ac.uk/Education-resources/Teaching-and-education/Big-Picture/All-issues/The-Cell/Image-galleries-Aspects-of-imaging/WTDV030896.htm fig 1 The chromosomes move to the middle

  6. Anaphase • Sister chromatids move to opposite ends http://image.tutorvista.com/content/feed/u1713/ http://commons.wikimedia.org/wiki/File:Cellule_en_anaphase.gif?uselang=fr?uselang=fr

  7. Telophase • Nuclear membrane reappears • Chromosomes loosen up http://mail.watertown.k12.ma.us:81/~kboudreau/Study%20Guides/wmssg/Gr7HP/Gr7SCI/SG/mitosis.htm http://www.tokresource.org/tok_classes/biobiobio/biomenu/cell_division/index.htm

  8. cytokinesis • Division of cytoplasm • Always moving to the next stage http://micro.magnet.fsu.edu/cells/fluorescencemitosis/cytokinesis1large.html http://iws.collin.edu/biopage/faculty/mcculloch/1406/notes/mitosis/cytokinesis.htm
