Know the 4 phases of mitosis and what happens in each.
Prophase- nuclear membrane disintegrates, the nucleolus disappears, chromosomes condense, and the spindle apparatus begins to form between the poles.
Metaphase- chromosomes attach to the spindle apparatus and align along the equator of the cell
Anaphase- microtubules shorten, moving chromosomes to opposite poles
Telophase- chromosomes reach poles of the cell, nuclear envelope re-forms, nucleolus reappears, chromosomes decondense (pg.249)
