1 PROPHASE METAPHASE ANAPHASE TELOPHASE

2  Chromosomes condense and nucleoli disappear  Each duplicated chromosome becomes visible as distinct sister chromatids  Mitotic spindle begins to form in the cytoplasm Mitotic spindle  The nuclear envelope breaks down and the centrosomes move toward the poles of the cell  Mitotic spindle attaches to a specialized structure called the kinetochore kinetochore

6  Chromosomes convene on the metaphase plate

10  Sister chromatids separate and move toward opposites poles of the cell by the spindle  As this happens the cell begins to elongate toward the poles

14  Cell continues to elongate throughout the phase  The mitotic spindle breaks down  Nuclear envelope forms at each end of the cell  Chromosomes inside begin to unfold into chromatin

19  Mitotic Spindle- A network of microtubules formed during mitosis. These microtubules attach to the centromeres of the chromosomes and help draw the chromosomes.  Kinetochore- A disc of proteins located on the centromere, specialized to interact with the spindle fibers during mitosis.
