英文: During mitosis, sister chromatids remain joined by their centromere until anaphase.
中文: 在有丝分裂期间，姐妹染色单体在分裂后期之前都是通过着丝点连接的。

英文: In meiosis it is not until anaphase II that the centromere divides, the chromatids being termed daughter chromosomes after separation.
中文: 在减数分裂期间，直到分裂后期II两条染色单体才随着着丝点的分裂而彼此分开。

英文: The centromere is a specific genetic locus and remains relatively uncoiled during prophase, appearing as a primary constriction.
