定义：有丝分裂(mitosis)中的一期，此时每一个染色体丝(chromatids)分开且移动到微管纺锤体(microtubular spindle)的相反两极。

At the beginning of prophase the chromosomes each consist of two highly condensed chromatids attached to each other at a centromere .

Alternatively, like allopolyploids, they may arise by the nondisjunction of chromatids during the mitotic division of a zygote .

Next, during anaphase , the two sister chromatids of each chromosome split , and one from each pair is drawn toward each pole of the cell .

Anaphase The stage in mitosis or meiosis when chromatids are pulled toward opposite poles of the nuclear spindle.
