Stages of mitosis

Chromatin condenses into visible chromosomes

Nuclear envelope breaks down and disappears

Centrosomes move to opposite poles

Alignment in the middle

Chromosomes lineup along the equator

Spindle fibers attach to each of the sister chromatid

Pulling apart

Sister chromatids are pulled apart by spindle fibers

Separated chromatids move toward opposite poles of the cell

Chromosomes reach the poles and begin to decondense back into chromatin

Two nuclear envelopes reform around each set of DNA

Spindle fibers dissolve , cytokinesis begins alongside or right after
