Verified step by step guidance

Recall the main stages of mitosis: Prophase, Metaphase, Anaphase, and Telophase, each with distinct events.

Understand that sister chromatids are identical copies of a chromosome connected at a region called the centromere.

Identify that the separation of sister chromatids involves breaking the connections at the centromere, allowing them to move to opposite poles.

Recognize that this separation occurs specifically during Anaphase, when the spindle fibers pull the chromatids apart.

Confirm that in Prophase, chromosomes condense; in Metaphase, chromatids align at the cell equator; and in Telophase, chromatids reach the poles and the cell prepares to divide.
