  1. Cell Division

  2. Cell Division: Mitosis • Object: To study the various stages in mitotic division

  3. Cell Division • In eukaryotes, cell division occurs in two major stages. • The first stage, division of the cell nucleus, is called mitosis. • The second stage, division of the cell cytoplasm, is called cytokinesis.

  4. Chromosomes • Genetic information is passed from one generation to the next on chromosomes. • Before cell division, each chromosome is duplicated, or copied.

  5. Chromosomes Sister chromatids • Each chromosome consists of two identical “sister” chromatids. • Each pair of chromatids is attached at an area called the centromere. Centromere

  6. Cell Cycle Cell Division

  7. Mitosis • Mitosis • Biologists divide the events of mitosis into four phases: • Prophase • Metaphase • Anaphase • Telophase
