Anaphase Strasburger (1884) originally introduced this term for the stage of nuclear division when the contents of the nuclei were going back (Gk. ana) to their normal appearance, but from about 1905 he used the term in the now universally adopted sense of the stage of mitosis or of meiosis 1 or 2 when the daughter-chromosomes (or homologous chromosomes in meiosis 1) move towards opposite poles of the spindle.
