Describe the significant event occurs in each of the four stages of mitosis. I need help with this , I appreciate your help.

Prophase: chromosomes condense and spindle microtubules form. Nuclear membrane breaks apart. Spindle microtubules invade nuclear region.
Metaphase: chromosomes move to equator of cell
Anaphase: the two chromatids of each chromosome separate; each former chromatid is considered to be an individual chromosome. Spindle microtubules move the new chromosomes to opposite poles of cell.
Telophase: chromosomes relax into their extended state and nuclear envelopes reform around each new daughter nucleus.

Here’s a video from McGraw-Hill
