d) tightly linked together at a centromere

Sister chromatids, which are connected by a structure known as the centromere, are two identical copies of the same chromosome that are created by DNA replication. They are split apart during cell division, and each daughter cell obtains one copy of the chromosome. Cells may keep their genetic makeup over generations because to DNA duplication that occurs during the S phase of the cell cycle. Sister chromatids' main job is to ensure that every daughter cell created during cell division receives a whole set of chromosomes. They are connected to one another during mitosis via the centromere, a section of DNA that creates protein complexes.
