what happens during mitosis ?
FOUR PHASES: Prophase: The chromosomes condense and turn into 2-strand chromatids; the nuclear membrane disappears; centrosomes turn to asters and a spindle fiber begins to form. Metaphase: The chromosomes align at the center of the cell (equatorial plate) and each chromosome is attached to the spindle fiber Anaphase: The chromatids (1 strand) separate and the centromere divides, where each single strand chromatid ascends to opposite poles of the cell (polar ascension) Telophase: The cellular membrane cleaves and the nuclear membrane appears again and the asters turn into centromeres once again I got this from a website :) http://answers.yahoo.com/question/index?qid=20110621220448AAf5HIH
