describe what happens during each of the four phases of mitosis?

Answer 1

Prophase: Chromatin condenses into chromasomes. Centrosomes form from microtubules and move apart from each other.

Metaphase: The chromosomes are aligned at the center of the cell by the action of the microtubules.

Anaphase: The chromosomes separate into identical halves (The genetic material replicates itself before mitosis begins.) which move towards opposite centrosomes, which move further apart.

Telophase: The chromosomes unfold and are reenveloped in new nuclei, while the microtubules complete the reshaping of the new cells.

Answer 2

Chromosomes replicate themselves to make identical sister chromosomes called "chromatids"

1. Prophase - The two chromatids remain attached to each other by the centromere, the nucleus break down and disappear.

2. Metaphase - Nuclear division becomes complete.

3. Anaphase - The two chromatids separate into thier own cells (called daughter cells),

4. Telophase the nucleaus forms in the two daughter cells.

Hope that helped.

Answer 3

Prophase - the mitotic spindle begins to form. Polar and kinetochore fibers comprise the mitotic spindle. Chromosomes continue to condense.
Metaphase - The chromosomes align on the plate in the center of the cell.
Anaphase - the sister chromatids separates.
Telophase - Mitotic apparatus disassembles.
