What are the phases of mitosis?

The phases of mitosis specifically refer to the stages that a cell goes through during the process of nuclear division. This process is critical for cellular reproduction and occurs in a defined sequence that includes Prophase, Metaphase, Anaphase, and Telophase.

During Prophase, chromosomes condense and become visible, and the mitotic spindle begins to form. In Metaphase, the chromosomes align at the cell's equatorial plane. Anaphase follows, where sister chromatids are pulled apart to opposite poles of the cell. Finally, Telophase involves the reformation of the nuclear envelope around each set of chromosomes, which then begin to decondense in preparation for the ensuing cell division.

This sequence captures the essential events that occur during mitosis, making it the correct description of the phases of mitosis. Understanding these stages is crucial for comprehending how cells replicate and how errors in this process can lead to cancer and other diseases.
