Solution

The correct option is D All of the above
A sister chromatid refers to either of the two identical copies (chromatids) formed by the replication of a single chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said as 'one-half' of the duplicated chromosome. They are created when DNA is replicated, they are separated during mitosis and they are attached at the centromere prior to division.
