    the kinetochore becomes attached to the mitotic spindle, sister chromatids line up at the metaphase plate, the kinetochore breaks apart and the sister chromatids separate, the nucleus re-forms and the cell divides

  • 2

    What is the name of the first phase of mitosis?

    Prophase

  • 3

    What happens to the nuclear envelope during prophase?

    It starts to break into small vesicles

  • 4

    What happens to the Golgi apparatus and endoplasmic reticulum during prophase?

    They fragment and disperse to the periphery of the cell

  • 5

    What happens to the nucleolus during prophase?

    It disappears

  • 6

    Where do the centrosomes begin to move to during prophase?

    To opposite poles of the cell

  • 7

    What happens to the microtubules that form the basis of the mitotic spindle during prophase?

    They extend between the centrosomes, pushing them farther apart

  • 8

    What happens to the sister chromatids during prophase?

    They begin to coil more tightly and become visible under a light microscope

  • 9

    What happens to many processes begun in prophase during prometaphase?

    They continue to advance

  • 10

    What happens to the remnants of the nuclear envelope during prometaphase?

    They disappear

  • 11

    What happens to the mitotic spindle during prometaphase?

    It continues to develop

  • 12

    What happens to the chromosomes during prometaphase?

    They become more condensed and visually discrete

  • 13

    How do sister chromatids attach to spindle microtubules?

    Via a protein complex called the kinetochore

  • 14

    Where are the chromosomes aligned during metaphase?

    In a plane called the metaphase plate, midway between the two poles

  • 15

    What is the state of the sister chromatids during metaphase?

    They are still tightly attached to each other

  • 16

    What is the state of the chromosomes during metaphase?

    They are maximally condensed
