WebMar 24, 2024 · In anaphase of mitosis and anaphase II of meiosis, the abrupt shortening of the spindle microtubules separates each chromatid into a pair of chromosomes and pulls them to opposite ends of the cell. This ensures that each of the daughter cells will receive a complete set of chromosomes. WebAnaphase (from Ancient Greek ἀνα- ( ana-) 'back, backward', and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell. Chromosomes also reach their overall maximum ...
