Interphase

Prophase Metaphase

Anaphase

Telophase

Where are chromosomes

pulled apart?

Where do cells double in

size?

When do centrioles form

spindle fibers?

When do chromosomes line

up in the middle of the cell?

When will the cell have two

identical nuclei?

Answer: The chromosomes of each pair are pulled towards opposite ends of the cell.

Explanation: In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein "glue" that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome.
