Mitosis Phases

Prophase

1. chromosomes condense

2. spindle fibers from centrosome

3. nuclear envelope breaks down

Prometaphase

1. kinetochores at centrosome

2. spindle microtubules attach to kinetochores

3. centrosomes moves to opposite poles

Metaphase

1. chromosomes lined up at metaphase plate

2. sister chromatid attached to spindle fiber from opposite pole

Anaphase

1. cohesin protein breaks sister chromatid

2. chromosomes pulled to opposite pole

3. non kinetochore fiber elongate cell

Telophase

1. chromosomes decondense

2. nuclear envelope surrounds each set of chromosomes

3. spindle breaks down

Cytokinesis

a cleavage furrow separates the daughter cells
