Final answer:
Mitosis consists of four main stages: prophase, where chromosomes become visible; metaphase, where chromosomes align at the equator; anaphase, where chromatids are pulled apart; and telophase, where two new nuclei form.
Step-by-step explanation:
Mitosis is a critical phase of the eukaryotic cell cycle, facilitating the division of a single cell into two genetically identical daughter cells. The process of mitosis is subdivided into four main stages: prophase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into more visible structures known as chromosomes, and the nuclear envelope disintegrates. In the subsequent stage, metaphase, the chromosomes align at the cell's equator. During anaphase, sister chromatids are separated and pulled to opposite poles of the cell. Finally, in telophase, the nuclear envelope re-forms around each set of separated chromosomes, leading up to cytokinesis, which physically divides the cell into two.
The correct order of events in mitosis is as follows: prophase, metaphase, anaphase, and telophase.
