3. Phases
Interphase (Not Dividing) Chromatin (DNA) loosely coiled DNA replicated Nuclear membrane intact PROPHASE (First Phase) Chromosomes shorten, thicken and become individualized Nuclear membrane disappears Centrioles move to ends of cell Spindle fibers attach to chromosomes METAPHASE (Second Phase) Chromosomes line up at middle of cell Spindle fibers start pulling chromosomes Chromosomes line up across middle of cell (equatorial plate) ANAPHASE (Shortest Phase) Spindle fibers pull chromosomes to opposite end of the cell Cell elongates TELOPHASE (Last Phase) Nuclear membrane reforms Chromosomes become coiled Centrioles return to their place Cytokinesis (Division of the cytoplasm) Cytoplasm divides by the time the nuclear membrane reforms
