Which term describes a chromosome that has been duplicated and consists of two sister chromatids?

Explanation:
When a chromosome has been duplicated, it now contains two identical copies called sister chromatids that stay connected at the centromere. This configuration is described as a replicated chromosome. The term captures both the duplication event and the fact that two chromatids are present as part of one chromosome unit. In contrast, an unreplicated chromosome has only a single chromatid, and the term sister chromatids refers to the two copies themselves rather than to the chromosome as a unit. During cell division, the replicated chromosome is prepared to split so the chromatids become separate chromosomes.
