What event occurs during cytokinesis?

During cytokinesis, the final stage of cell division occurs, which completes the process of dividing the cytoplasm of a parental cell into two daughter cells. This event follows mitosis, where the genetic material is separated into two nuclei. During cytokinesis, structures such as the contractile ring form, leading to the physical division of the cell. This is essential for ensuring that each daughter cell receives an appropriate share of the cytoplasm and organelles, essentially resulting in two distinct, individual cells, each with its nucleus and cellular machinery ready for the next phase of growth or division.

The other choices address events that occur at different stages of the cell cycle or cell division process: chromosomes condensing occurs during prophase, DNA replication takes place during the S phase of interphase, and chromatids separating happens during anaphase. Each of these processes is crucial for cell division but does not define the specific event that takes place during cytokinesis.
