Mitosis Fill-In Notes

Cell Division

MITOSIS - Nuclear division

Prophase

Metaphase

Anaphase

Telophase

Cytokinesis - Cytoplasm divides

G₀- cell stop dividing

(Ex: nerve cell)

Stages of Mitosis

Prophase

1st dividing phase

DNA (Chromatin) scrunches into chromosomes

Nuclear membrane & nucleolus disappear

Spindle fibers form & attach to chromosomes

Centrioles appear in centrosome region & move to poles

Centrosome egion organizes spindle

Spindle MICROTUBULES are part of cytoskeleton

Metaphase

Chromosomes line up in middle of the cell

Anaphase

Centromeres split

Centrioles pull chromatids apart

-Chromatid arms separate and

move to opposite ends of the cell

Telophase (See z nuclei)

"Reverse Prophase"

Nuclear membrane & nucleolus return

Chromosomes spread out

Centrioles disappear

Spindle fibers disappear

Cytokinesis

Cytoplasm splits into 2 cells
