Question

what are sister chromatids?

Answer 1

Sister chromatids. ... 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 to be 'one-half' of the duplicated chromosome.

Answer 2

Sister chromatids are a pair of synthesized daughter chromatids generated when a single chromosome is duplicated into two copies of the parent chromosome. The replication of these chromosomes occurs during the synthesis phase of interphase.
