What occurs to the sister chromatids during anaphase of mitosis?

During anaphase of mitosis, the sister chromatids, which are identical copies of a chromosome, are pulled apart and migrate toward opposite poles of the cell. This separation is facilitated by the spindle fibers that connect to the centromeres of each chromatid. As anaphase progresses, the cohesin proteins that hold the sister chromatids together are cleaved, allowing them to move independently. This action ensures that each daughter cell will receive an identical set of chromosomes during the subsequent stages of mitosis, leading to the successful division of the cell into two genetically identical cells.

The other processes mentioned occur at different stages of mitosis. For instance, the alignment of chromosomes along the metaphase plate happens in metaphase, while coiling into chromosomes and condensing into chromatin occur in earlier (prophase) and later stages (telophase or interphase) of the cell cycle, respectively.
