  1. 1. The Cell Cycle and Mitosis
  2. 3. First Growth Phase (G1) <ul><ul><li>Cell grows rapidly </li></ul></ul><ul><ul><li>Normal cell functioning </li></ul></ul><ul><ul><li>Major portion of life </li></ul></ul>
  3. 4. Synthesis Phase (S) <ul><ul><li>DNA is copied </li></ul></ul><ul><ul><li>Each chromosome = 2 chromatids attached at centromere </li></ul></ul>
  4. 6. Second Growth Phase (G2) <ul><ul><li>Organelles replicate </li></ul></ul><ul><ul><li>Microtubules form spindle to move chromosomes during mitosis </li></ul></ul>

  11. 16. REVIEW <ul><li>Humans have 23 sets of two chromosomes </li></ul><ul><li>One of each pair came from each parent. </li></ul><ul><li>SOMATIC cells (body cells) all contain 46 chromosomes </li></ul><ul><li>gametes(sperm and egg) are haploid, they contain 23 chromosomes each. </li></ul><ul><li>When gametes combine they form a diploid ZYGOTE . </li></ul>

  15. 20. Meiosis Mitosis Start with 2N cells, end with 1N cells (haploid.) Start with (diploid) 2N cells, End with 2N cells # of chromosomes in cells produced is reduced by half. Chromosome # stays the same. Creates 4 egg or sperm cells Creates 2 identical daughter cells <ul><li>2 Cell divisions involving </li></ul><ul><li>Interphase </li></ul><ul><li>Prophase </li></ul><ul><li>Metaphase </li></ul><ul><li>Anaphase </li></ul><ul><li>telophase </li></ul><ul><li>1 cell division involving </li></ul><ul><li>Interphase </li></ul><ul><li>Prophase </li></ul><ul><li>Metaphase </li></ul><ul><li>Anaphase </li></ul><ul><li>telophase </li></ul>
