Cell Cycle http://alevelnotes.com/content_images/i77_dwa_1_mitosis.gif
Interphase • 90% of cell life in this stage • grows • DNA replicates (exact copy) • prepares to divide http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/bio%20101/bio%20101%20lectures/mitosis/whitefish_mitosis_interphase_X_400_small.jpg http://local.brookings.k12.sd.us/biology/images/mitosis-animated.gif
Mitosis This stage has four stages within itself. These stages are: • Prophase • Metaphase • Anaphase • Telophase http://img.tfd.com/dorland/thumbs/mitosis.jpg
Prophase • nuclear membrane and nucleolus disappear • spindle fibers (ropes) appear • see duplicated chromosomes http://www.microscopy-uk.org.uk/mag/imgnov04macro/prophase.jpg http://www.monteweston.com/Biology/Bio/label41.jpg
Metaphase • Duplicative chromosomes • Sister chromatids on either sides http://student.ccbcmd.edu/~gkaiser/biotutorials/dna/mitosis/images/metaphase1_pc.jpg http://www.clker.com/cliparts/b/d/e/f/12641392951083079626Metaphase_procariotic_mitosis.svg.hi.png
Anaphase • sister chromatids separate • move to opposite sides http://www2.sunysuffolk.edu/gambier/micrographs/anaphaseI2.JPG http://thumbs.dreamstime.com/thumblarge_448/12567407355rx4OM.jpg
Telophase • nuclear membrane and nucleolus reappear • chromosomes loosen up and become chromatin http://www.baileybio.com/plogger/thumbs/lrg-207-telophase_-_animal_cell__whitefish_blastula_.jpg http://www.phschool.com/science/biology_place/biocoach/images/meiosis/metel1.gif
Cytokensis • division of cytoplasm • always moving to the next stage http://botit.botany.wisc.edu/Resources/Botany/Mitosis/Allium/telophase%20cytokinesis.jpg http://www.biologycorner.com/resources/cytokinesis.gif
