Which of the following best describes the concept of interphase in cell division?

Interphase is the critical phase in the cell cycle where the cell prepares itself for division, but it is not a stage of division itself. During interphase, which precedes mitosis, the cell is actively engaged in growth, DNA replication, and the preparation of various cellular components necessary for successful division. This is why describing interphase as the resting phase before mitosis begins is accurate, even though it is a time of considerable activity rather than inactivity.

While interphase is essential for ensuring that the cell is ready to enter mitosis, it should not be conflated with the actual events of mitosis, such as chromosome alignment or separation, which occur in later phases of the cell cycle. Therefore, understanding interphase as a preparatory phase helps clarify its role in the overall process of cell division.
