Presentation Transcript

  1. Cell Cycle Interphase Mitosis

  2. Interphase • Cell normally functioning • Phase cell is in most of the time • G1, G0, S, G2

  3. Mitosis-PMAT • Prophase-Prepare • Metaphase-Middle • Anaphase-Apart • Telophase-THE END

  4. Prophase-PREPARE • Cell PREPARES to divide • Centrioles get into place • Spindle fibers form • Chromosomes condense • Nuclear envelope dissolves

  5. Metaphase-MIDDLE • Chromosomes line up in the MIDDLE of the cell

  6. Anaphase-APART • Chromosomes are pulled APART by the centrioles and spindle fibers

  7. Telophase-THE END • The chromosomes are at each end of the cell and nuclear envelops form • The cell divides in two-Cytokinesis • THE END

  8. What does PMAT stand for? Prophase Metaphase Anaphase Telophase Prepare Middle Apart THE END

  9. Mitosis

  10. Controls on Cell Division • Cells only divide when growth is needed • Cyclins and Cyclin Dependent Kinases (CDK) are proteins that regulate the timing of the cell cycle

  11. Uncontrolled Cell Growth • When cells lose the ability to control growth it results in a mass of cells called a tumor. • Benign tumors • Do not metastasize (spread) • Malignant tumors-Cancer • Metastasize

  12. Skin Cancer

  13. Lung Cancer

  14. Cancer
