Cell Division By: Courtney Ayers
The Three Stages of Cell Division • Interphase • Mitosis • Cytokinesis
Interphase • is the phase of the cell cycle in which the cell spends the majority of its time, it grows DNA replicates, and prepares to divide. http://mail.watertown.k12.ma.us:81/~kboudreau/Study%20Guides/wmssg/Gr7HP/Gr7SCI/SG/mitosis.htm http://staff.jccc.net/pdecell/expression/control.html
Mitosis • is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components http://www.sciencegeek.net/Biology/review/U3Review.htm http://en.wikipedia.org/wiki/File:Atypical_mitosis.jpg
Cytokinesis • is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells and is the division of cytoplasm. http://www.biologylessons.sdsu.edu/ta/classes/lab8/TG.html http://www.edupic.net/cells.htm
The 4 stages of Mitosis • Prophase • Metaphase • Anaphase • Telophase
Prophase • Nuclear membrane + nucleolus disappears, spindle fibers appear and the chromatin condenses into double rod-shaped structures called chromosomes. http://www.monteweston.com/Biology/Preeti.html • http://washington.uwc.edu/about/wayne.schaefer/MitosisPage.htm
Metaphase • It’s DNA, duplicated chromosomes move to the middle, and sister chromatids on either side. http://staff.jccc.net/pdecell/celldivision/mitosis1.html http://faculty.ccbcmd.edu/~gkaiser/biotutorials/dna/mitosis/acmetaphase.html
Anaphase • is the stage of mitosis when sister chromosomes move to opposite poles of the cell. . • http://www.fractalposter.com/fractals/anaphase-1514.html • http://www.synapses.co.uk/genetics/tsg3.html
Telophase • Nuclear membrane + nucleolus reappear, chromosomes loosen up, and they become chromatin. http://en.wikipedia.org/wiki/File:Telophase.jpg http://www.sparknotes.com/biology/cellreproduction/mitosis/section3.rhtml
