    Chromosome - chromatin that has condensed into a compact shape

    Centriole - attachment site for chromosomes during cell division

    Cell Division = Mitosis + Cytokinesis

    * Remember the chromosomes have already duplicated prior to Mitosis

    Prophase

    - chromosomes appear (condensed)

    - centrioles begin to move to opposite ends of the cell

    - nuclear membrane begins to disappear

    - spindle fibers form

  • Lesson 1 Cell Division + Mitosis.notebook April 25, 2020

    Metaphase

    - Chromosome line up across equator (center) of cell

    - spindle fiber attaches at the centromere

    Anaphase

    - sister chromatids separate

    - attached to a spindle fiber and begin to be pulled toward centriole

    Telophase

    - chromosomes de condense

    - nuclear membrane forms around each group of chromatin

    Cytokinesis occurs next

    - cell pinches off into 2 new daughter cells

    - cytokinesis is part of the M phase but not part of Mitosis

    * The cells are now ready to enter interphase
