Anaphase
Metaphase
Prophase

Nucleoli disappear

Chromatin fibers coil tightly forming chromosomes

Mitotic spindle begins to form

Centrosomes move to opposite poles of the cell

Nuclear envelope fades away

Spindles form between the centrosomes

Each chromatid develops a kinetochore

Microtubules attach to kinetochores

Prophase
Metaphase

Chromosomes align on the metaphase plate

Each chromosome attaches to kinetochore microtubule
Anaphase

Shortest phase of mitosis

Microtubules retract to both poles of the cell

Each microtubule carries 1 chromatid by the kinetochore

Cell begins elongating
Telophase

2 different nuclear envelopes form around the chromatids

Nucleoli reappears

Chromosomes uncoil

Cell divides at the cleavage furrow
Terms

Chromatin – Entire complex of DNA and proteins that is the building material
of chromosomes

Mitotic Spindle – A structure composed of centrosomes and microtubules that
spans the cell during mitosis

Centrosomes – Organelles that aid the cell in mitosis via the mitotic spindle

Metaphase plate – Plane that is equidistant from both of the spindles’ poles

Kinetochore – Binding spot found on chromatids for the spindles

Cleavage Furrow – Area in which the cell divides after mitosis
