Verified step by step guidance

Understand the stages of mitosis: Mitosis is divided into several phases: prophase, prometaphase, metaphase, anaphase, and telophase. Each phase has distinct events that occur within the cell.

Identify the role of sister chromatids: Sister chromatids are identical copies of a chromosome connected by a centromere. They are crucial for accurate genetic material distribution during cell division.

Review the events of each mitotic phase: In prophase, chromosomes condense and become visible. In prometaphase, the nuclear envelope breaks down, and spindle fibers attach to chromosomes. In metaphase, chromosomes align at the cell's equatorial plane.

Focus on anaphase: During anaphase, the centromeres split, and the sister chromatids are pulled apart by the spindle fibers toward opposite poles of the cell. This separation is a key event in ensuring each daughter cell receives an identical set of chromosomes.

Conclude with telophase: In telophase, the separated chromatids reach the poles, and the nuclear envelope re-forms around each set of chromosomes, completing the process of mitosis.
