<P> A sister chromatid refers to the identical copies ( chromatids ) formed by the replication of a chromosome , with both copies joined together by a common centromere . In other words , a sister chromatid may also be said to be ' one - half ' of the duplicated chromosome . A full set of sister chromatids is created during the synthesis ( S ) phase of interphase , when all the chromosomes in a cell are replicated . The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis . </P>
