Select a step of mitosis:
Prophase: Nucleus begins to break down, Chromatin condenses into chromosomes, Spindle fibers begin to form, Centrosomes move to opposite poles of the cell
Prometaphase: Nuclear envelope completely breaks down, Spindle fibers attach to chromosomes at kinetochores, Chromosomes start to move towards the center of the cell
Metaphase: Chromosomes align at the cell’s equator, Spindle fibers fully extend from each centrosome to the chromosomes
Anaphase: Sister chromatids separate and move towards opposite poles, Cell elongates as the poles move apart, Each pole receives an equal number of chromosomes
Telophase: Chromosomes reach the poles and begin to decondense, Nuclear envelope reforms around each set of chromosomes, Spindle fibers disassemble
