Nuclear envelope breaks down.

Explanation: During prophase (and especially prometaphase) the chromatin condenses into visible chromosomes, the nucleolus disappears and the nuclear envelope breaks down so the spindle can attach. Chromosomes lining up at the equator is metaphase, sister chromatids separating is anaphase, and cytokinesis begins at the end of mitosis/telophase.
