Understanding the Cell Cycle: Key Phases of Mitosis Explained

This guide provides an overview of the essential phases of the cell cycle, focusing on mitosis. It details the stages: Interphase (growth and DNA replication), Prophase (nuclear membrane breakdown and spindle fiber formation), Metaphase (chromosomes align), Anaphase (sister chromatids separate), Telophase (nuclear membranes reform), and Cytokinesis (cell division completion). Each phase is crucial for proper cell division, ensuring that genetic material is accurately duplicated and distributed. Explore the links for visual aids and further information on each stage of mitosis.

  1. Cell Cycle By: Anette Aguilera

  2. Interphase • grow • DNA replicates (exact copy) • prepares to divide http://botit.botany.wisc.edu/Resources/Botany/Mitosis/Allium/Various%20views/interphase.jpg.html http://mail.watertown.k12.ma.us:81/~kboudreau/Study%20Guides/wmssg/Gr7HP/Gr7SCI/SG/mitosis.htm

  3. Prophase • nuclear membrane and nucleus disappear • spindle fibers appear(ropes) • see duplicate chromosomes http://users.csc.calpoly.edu/~zwood/teaching/csc471/finalproj25/cschell/ http://www.auburnschools.org/drake/jwilliams/cell_cycle.htm

  4. Anaphase • sister chromatids separates and move to opposite ends http://www2.sunysuffolk.edu/gambier/micrographs/anaphase.htm http://www.vietnamen.org/bio/?tag=anaphase

  5. Metaphase • duplicated chromosomes move to the middle • sister chromatids on either side http://www.proprofs.com/quiz-school/story.php?title=plant-and-animal-cells-quiz_1 http://www.rci.rutgers.edu/~uzwiak/AnatPhys/Mitosis/Mitosis.html

  6. Telophase • nuclear membrane and nucleolus reappear • chromosomes loosen up and become chromatin http://buildmakecraftbake.com/2009/01/art-on-job-biology-under-microscope.html http://www.edupic.net/cells.htm

  7. Cytokinesis • always moving to the next stage http://www.visualphotos.com/image/1x3743050/epithelial_cell_in_cytokinesis_cell_division_color http://uvs-model.com/UVS%20on%20unisonal%20evolution%20mechanism.htm
