Mitosis Prophase: Nuclear envelope dissapears, chromatin condenses, Centrioles appear, spindle fibers start to form, Sister chromatids appear Metaphase: Chromosomes (sister chromatids) line up along the center of the cell Anaphase: spindle fibers attach to centromeres Telophase: centromeres split in half, sister chromatids split in half Cytokinesis: cytoplasm replicates, the cell fully divides, and we have produce 2 diploid cells , or daughter cells
