  4. Where Does Mitosis Occur in a Cell’s Life? Back

  5. Prophase • Chromatin separates into chromosomes • Nuclear envelope breaks down • Centrioles begin to move towards the poles of the cells • Spindles (formed by microtubules) begins to form between the poles Back

  6. Prophase Centrioles Chromosomes Nuclear Envelope Spindles Back

  7. Prophase Back

  8. Metaphase • Spindle fibers begin to attach to the centromeres of each pair of sister chromatids • The sister chromatids move towards and line up in the center of the cell Back

  9. Metaphase Spindle Fibers Sister Chomatids Centromeres Back

  10. Metaphase Back

  11. Anaphase • Spindle fibers shorten and separate the sister chromatids • Centromeres separate • At the end of this phase, each pole of the cell will have a complete set of chromosomes Back

  12. Anaphase Centriole Chromatid Centromere Spindle Fibers Back

  13. Anaphase Back

  14. Telophase • Chromosomes uncoil and form chromatin • Spindles break down • Nuclear membranes form again Back

  15. Telophase Chromatin Nuclear Membranes Back

  16. Telophase Back

  17. Cytokinesis • The cytoplasm splits into two and the cell divides • The plasma membrane pinches the cell in the middle until two daughter cells form. Back

  18. Cytokinesis Cytoplasm Chromatin Daughter Cells Back

  19. Cytokinesis Back
