1) The document describes the stages of mitosis: interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis.
2) During interphase, DNA is copied and centrioles divide. In prophase, DNA condenses into chromosomes. In prometaphase, the nuclear envelope breaks down and spindles attach to chromosomes.
3) Metaphase aligns chromosomes in the center. Anaphase separates sister chromatids. Telophase and cytokinesis complete cell division into two daughter cells ready for the next cycle.
