Interphase

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

4
Mitosis-PMAT

• Prophase-Prepare
• Metaphase-Middle
• Anaphase-Apart
• Telophase-THE END

5
Prophase-PREPARE

• Cell PREPARES to divide
• Centrioles get into place
• Spindle fibers form
• Chromosomes condense
• Nuclear envelope dissolves

6
Metaphase-MIDDLE

• Chromosomes line up in the MIDDLE of the cell

7
Anaphase-APART

• Chromosomes are pulled APART by the centrioles
  and spindle fibers

8
Telophase-THE END

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

9
What does PMAT stand for?

• Prophase ?Metaphase ?Anaphase ?Telophase
• Prepare ?Middle ?Apart ?THE END

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

13
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
