mitosis

prophase

Chromosomes condense and become visible

prophase

Spindle fibers emerge from the centrosomes

prophase

Nucicar envelope breaks down

prophase

Centrosomes move toward opposite poles

prometaphase

Chromosomes continue to condense

prometaphase

Kinetochores appear at the centromeres

prometaphase

Mitotic spindle microtubules
attach to kinetochores

metaphase

chromosomes are lined up at the metaphase plate

metaphase

Each sister chromatid is attached to a spindle liber originating from opposite poles

anaphase

Centromeres split in to

anaphase

Sister chromatids (now called
chromosomes are pulled toward opposite poles)

anaphase

Certain spindia fibers begin to elongate the cell

telophase

Chromosomes arrive at opposite poles and begin to decondense

telophase

Nuclear envelope material surrounds each set of chromosomes

telophase

The mitotic spindle breaks down

telophase

Spindle fibers continue to push poles apart
