TELOPHASE

PROPHASE Chromosomes condense and

nucleoli disappear Each duplicated chromosome

becomes visible as distinct sister chromatids

Mitotic spindle begins to form in the cytoplasm

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

ANAPHASE 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

the phase The mitotic spindle breaks down Nuclear envelope forms at each end of

the cell Chromosomes inside begin to unfold

into chromatin

DEFINITIONS 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.
