Cell Cycle

  1. 1. Cell Cycle Josh Rolfe Start the Tour
  2. 2. Interphase Prophase Cytokinesis Telophase Anaphase Metaphase The Cell Cycle
  3. 3. Interphase <ul><li>The cell grows to its mature size, makes a copy of its DNA , and prepares to divide into 2 cells. </li></ul>Back
  4. 4. Prophase <ul><li>the chromatin in the nucleus condenses to form the chromosomes. Structures called spindle fibers form a bridge between the ends of the cell. The nuclear membrane breaks down. </li></ul>Back
  5. 5. Metaphase <ul><li>The chromosomes line up across the cell. Each chromosome attaches to a spindle fiber at its centromere, which still hold the chromatins together. </li></ul>Back
  6. 6. Anaphase <ul><li>The centromeres split. The two chromatids separate. One chromatid moves along the spindle fiber to one end of the cell. The other chromatid moves to the opposite end. The cell becomes stretched out as the opposite ends pull apart. </li></ul>Back
  7. 7. Telophase <ul><li>The chromosomes begin to stretch out and lose their rod like appearance. This occours in the two regions at the ends of the cell. A new nuclear membrane forms around each region of chromosomes. </li></ul>Back
  8. 8. Cytokinesis <ul><li>The cell membrane pinches in around the middle of the cell. Eventually the cell pinches in 2. Each daughter cell ends up with the same number of identical chromosomes and about half of the organelles in the cytoplasm. </li></ul>Back
