Study Notes
Mitosis - Metaphase
- Nuclear envelope disintegrates, chromosomes scattered in cytoplasm; condensation is completed for clear microscopic viewing.
- Ideal stage for chromosome morphology study.
- Metaphase chromosome is composed of two chromatids joined by a centromere.
- Kinetochores, small disc-like structures on the centromere, are attachment points for spindle fibers.
- Chromosomes move to the cell's center (equator).
- Each chromatid connects to spindle fibers from opposite poles via its kinetochore.
- The metaphase plate is the plane where chromosomes line up.
- Key features of metaphase: spindle fibers attach to kinetochores, chromosomes align at the metaphase plate, and spindle fibers move chromosomes.
