Flashcards

Metaphase

The stage of mitosis where chromosomes are aligned at the center of the cell, ready to be separated.

Centromere

The protein structure that connects sister chromatids together, ensuring accurate chromosome separation.

Kinetochores

Small disc-shaped structures on the centromere that serve as the attachment points for spindle fibers.

Spindle fibers

Microtubule structures that extend from the poles of the cell and attach to chromosomes, guiding their movement to the equator.

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.
