The Cell Cycle

  1. 1. The Cell Cycle<br />Cells undergoing changes due to the cell cycle<br />
  2. 2. Introduction<br />The cell cycle consists of two parts: <br />Interphase<br />The mitotic phase (mitosis)<br />A cell in interphase – G1<br />
  3. 3. Interphase<br />This is a time when it just performs its function normally<br />Made up of three periods:<br />G1: the cell grows<br />S: duplication of the cell’s DNA occurs<br />G2: the cell prepares to divide<br />The cell cycle in a pie chart<br />
  4. 4. Mitosis<br />This is the time when the cell needs to divide<br />Made up of five periods:<br />Prophase<br />Metaphase<br />Anaphase<br />Telophase<br />Cytokinesis<br />The periods of mitosis<br />
  5. 5. Prophase<br />The chromatin condense into chromosomes<br />The nuclear envelope disappears<br />Nuclear envelope disappearing<br />Chromatins condensing<br />
  6. 6. Metaphase<br />The chromosomes align at the equatorial plate<br />Chromosomes aligning<br />
  7. 7. Anaphase<br />The sister chromatids separate<br />The centromeres divide<br />Separation of sister chromatids<br />
  8. 8. Telophase<br />The chromatin expands<br />Chromatin expanding<br />
  9. 9. Cytokinesis<br />The cytoplasm divides<br />Cytoplasm divides<br />
