Organigram

The stages of mitosis include prophase, metaphase, anaphase, and telophase, each with distinct cellular activities. In prophase, duplicated chromosomes become visible, consisting of sister chromatids connected by centromeres, and the spindle apparatus forms as the nuclear envelope disintegrates.
