CELL MODEL

MITOSIS MODEL

Interphase

Nucleus is intact. Centrioles are close together

MITOSIS MODEL

MITOSIS MODEL

Early Prophase

Centrioles are moving apart.

Nucleus (with chromatin) is still intact.

MITOSIS MODEL

MITOSIS MODEL

Late Prophase

Centrioles are at opposite ends. Nucleus breaks apart, forming chromosomes.

MITOSIS MODEL

MITOSIS MODEL

Metaphase

Chromosomes are aligned in the middle of the cell

forming sister chromatids.

Spindle Fiber

MITOSIS MODEL

MITOSIS MODEL

Anaphase

Sister chromatids separate forming

daughter chromosomes.

MITOSIS MODEL

MITOSIS MODEL

Late Anaphase

Daughter chromosomes become further separated.

MITOSIS MODEL

MITOSIS MODEL

Telophase

Chromosomes have completed their

separation forming new nuclei. Cytokinesis causes

cleavage furrow.

MITOSIS MODEL

MITOSIS MODEL

Daughter Cells/ Interphase

Cytokinesis has been completed. We now have 2

individual cells.

(Note cell boundary between cells.)
