What are the phases of mitosis?

The phases of mitosis are correctly identified as prophase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. Metaphase follows, where chromosomes align at the cell's equatorial plate, ensuring that each daughter cell will receive an identical set of chromosomes. Anaphase is the stage where the sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers. Finally, during telophase, the chromatids reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

The phases all represent critical steps in the process of somatic cell division, which facilitates the equal distribution of genetic material into the daughter cells. Each step is essential for ensuring that cell division occurs accurately and efficiently, thus maintaining genetic stability within an organism. The absence of interphase, cytokinesis, or any other sequence in this correct choice affirms its focus specifically on the stages that define mitosis itself.
