Understand the process of mitosis: Mitosis is the division of a single cell into two genetically identical daughter cells. It consists of several phases: prophase, metaphase, anaphase, and telophase.
Review the role of sister chromatids: Sister chromatids are identical copies of a chromosome that are connected by a centromere. During mitosis, they are separated to ensure each daughter cell receives an identical set of chromosomes.
Analyze the events of each phase: In metaphase, sister chromatids align at the cell's equatorial plane. In anaphase, the sister chromatids are pulled apart to opposite poles of the cell. In prophase, chromosomes condense and spindle fibers form. In telophase, the chromosomes reach the poles and the nuclear envelope begins to reform.
Focus on anaphase: During anaphase, the spindle fibers shorten, pulling the sister chromatids apart at the centromere. This ensures that each pole of the cell receives one copy of each chromosome.
Conclude that the phase where sister chromatids move to opposite poles of the cell is anaphase, based on the description of mitotic events.
