mitosis phase

Prophase

Prophase

Chromosomes condense. Centrosomes radiate microtubules and migrate to opposite poles

Prometaphase

the nuclear membrane breaks down and the microtubules of the mitotic spindle attach to the chromosomes

Prometaphase

microtubules grow and shrink to explore the region that was once the nucleus. microtubules encounter chromosomes, they attach to the chromosomes at their centromeres.

Metaphase

chromosomes align along a single plane in the middle of the dividing cell. The spindle microtubules lengthen and shorten

Metaphase

During this stage, the chromosomes are lined up in a single plane that is roughly equidistant from both of the spindle poles.

Anaphase

the centromere divides and kinetochore microtubules shorten, pulling the chromatids apart toward the centrosome.

Anaphase

ensures that one chromatid from each pair of sister chromatids goes to opposite poles of the cell

Telophase

A complete set of chromosomes is now at each pole of the cell. the microtubules break down completely and the nuclear envelope re-forms.
