The correct sequence of the phases of mitosis is indeed best represented by the choice provided, which names the stages as interphase, prophase, metaphase, anaphase, and telophase.

To clarify this progression:

  • Interphase is the phase where the cell prepares for division, growing and duplicating its DNA. While it is not a mitotic phase per se, it is included in the overall process of the cell cycle.

  • Prophase follows interphase, characterized by the condensation of chromatin into visible chromosomes. The nuclear envelope begins to break down, and the mitotic spindle starts to form.

  • In metaphase, the chromosomes align at the equatorial plane of the cell, known as the metaphase plate, ensuring they are properly positioned for segregation.

  • Anaphase is marked by the separation of sister chromatids, which are pulled toward opposite poles of the cell by the spindle fibers.

  • Finally, telophase occurs, where the chromatids reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Understanding the order of these phases is crucial for grasping how cells divide and replicate in the process of growth and development.
