Verified step by step guidance

Understand the process of mitosis, which is the division of a single cell into two genetically identical daughter cells. Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase.

Recognize that during metaphase, chromosomes are aligned at the metaphase plate, which is the imaginary line equidistant from the two centrosome poles. This alignment ensures that each daughter cell will receive an identical set of chromosomes.

Recall that prophase is the phase where chromosomes condense and become visible, and the mitotic spindle begins to form, but chromosomes are not yet aligned in the center.

Identify that anaphase is the phase following metaphase, where sister chromatids are pulled apart toward opposite poles of the cell.

Note that telophase is the final phase of mitosis, where the chromosomes arrive at the poles, and the nuclear envelope re-forms around each set of chromosomes, completing the division process.
