Final answer:
During interphase, DNA replication occurs as the cell prepares for division. This phase involves cell growth and preparation for mitosis, which is the actual phase when cell division and cytokinesis occur.
Step-by-step explanation:
The correct answer to which of the following occurs during interphase is B. DNA replication. Interphase is a phase of the cell cycle in which the cell grows, increases in size, and prepares for cell division. This period comprises three stages: G1, S, and G2. During the G1 stage, the cell experiences growth and protein synthesis. The following S phase is characterized by DNA replication, during which each chromosome in the nucleus is duplicated. Finally, in the G2 stage, there is further cell growth and protein synthesis, preparing the cell for division. Interphase is followed by the mitotic phase, where chromosome segregation happens, and cytokinesis, where the cytoplasm divides into two daughter cells. Therefore, cell division, chromosome segregation, and cytokinesis do not occur during interphase but rather in the subsequent mitotic phase.
