Understanding Cell Division: Stages of Mitosis and Cytokinesis Explained

Cell division is essential for growth, development, and tissue repair in living organisms. This comprehensive guide details the stages of cell division: Interphase, where DNA replicates and prepares for division; Mitosis, which encompasses Prophase, Metaphase, Anaphase, and Telophase. During Mitosis, chromosomes are duplicated and segregated into two nuclei. Finally, Cytokinesis occurs, dividing the cytoplasm and completing cell division. This process is vital in ensuring that each daughter cell receives an exact copy of the genetic material.

  1. Cell division http://ghr.nlm.nih.gov/handbook/howgeneswork/cellsdivide By: tasheonnawalton

  2. Stage 1:Interphase(prep stage) http://mail.watertown.k12.ma.us:81/~kboudreau/Study%20Guides/wmssg/Gr7HP/Gr7SCI/SG/mitosis.htm http://biology.uoregon.edu/reference/ort_mitosis/interphase.html Grows DNA replicates (exact copy) Prepare to divide

  3. Stage2:Mitosis (division of nucleus) 4 phases: Prophase, Metaphase, Anaphase, Telophase

  4. Prophase http://student.ccbcmd.edu/~gkaiser/biotutorials/dna/mitosis/acprophaseA.html http://staff.jccc.net/pdecell/celldivision/mitosis1.html Nuclear membrane and nucleolus disappear Spindle fibers appear (ropes) See duplicated chromosomes Mitosis : phase 1

  5. Metaphase http://www.sparknotes.com/biology/cellreproduction/mitosis/section2.rhtml http://www.quia.com/jg/1818412list.html Mitosis: phase 2 Duplicated chromosomes Move to the middle sister chromosomes on either side

  6. Anaphase: (moves away) http://student.ccbcmd.edu/~gkaiser/biotutorials/dna/mitosis/pcanaphaseA.html http://en.wikipedia.org/wiki/File:Anaphase.jpg Mitosis: phase3 Sister chromosomes separate and move too opposite ends

  7. Telophase (two) http://student.ccbcmd.edu/~gkaiser/biotutorials/dna/mitosis/pctelophaseA.html Nuclear membrane and nucleolus reappear Chromosomes loosen up and become Mitosis: phase4 uic.edu

  8. Stage 3: cytokinesis Always moving to the next stage http://essayweb.net/biology/celldivision.shtml http://micro.magnet.fsu.edu/cells/fluorescencemitosis/cytokinesis1large.html
