#spindle fibers

• Anaphase — The third consecutive stage of the cell division process (mitosis or meiosis), structurally characterized by the abrupt separation and simultaneous migration of sister chromatids or homologous chromosomes toward the opposite poles of the cell. This mechanical and biological phenomenon, coordinated by the contraction of the mitotic spindle fibers, guarantees the perfectly equal and exact distribution of the duplicated genetic material to the two future daughter cells.
