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.)
