What are the different phases of mitosis?

The correct answer identifies the specific stages of mitosis, which are integral to the process of cell division. Mitosis is a series of phases that ensure the accurate segregation of replicated chromosomes into two daughter cells.

The four phases of mitosis include prophase, metaphase, anaphase, and telophase.

• In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. The mitotic spindle starts to form from the centrosomes.

• During metaphase, the chromosomes align at the metaphase plate, or equatorial plane, of the cell, with spindle fibers firmly attached to the centromeres of the chromosomes.

• Anaphase follows, where sister chromatids are pulled apart towards opposite poles of the cell due to the shortening of the spindle fibers.

• Finally, in telophase, the separated chromatids reach the poles, and the nuclear envelope re-forms around each set of chromosomes, which begin to de-condense, leading into cytokinesis.

This sequence ensures that each daughter cell receives an identical set of chromosomes, which is critical for maintaining genetic stability through generations of cells. Other options incorrectly identify phases or elements outside of mitosis, such as interphase or
