Anaphase is a stage of mitosis during which the sister chromatids are pulled apart to opposite poles of the cell. This ensures that each new daughter cell will receive an identical set of chromosomes.
Mitosis: A process of cell division that results in two genetically identical daughter cells from a single parent cell.
Metaphase: The stage of mitosis where chromosomes align at the metaphase plate before being separated.
Sister Chromatids: Identical copies of a chromosome connected by a centromere, which are separated during anaphase.
