Verified step by step guidance

Step 1: Begin by understanding the process of mitosis, which is the division of a cell's nucleus into two identical nuclei. Mitosis consists of several stages: prophase, metaphase, anaphase, and telophase.
Step 2: Recall the sequence of mitosis stages. Prophase is the first stage where chromosomes condense and spindle fibers begin to form. Metaphase follows, where chromosomes align at the cell's equatorial plate. Anaphase is next, where sister chromatids are pulled apart to opposite poles of the cell.
Step 3: Understand that telophase is the final stage of mitosis. During telophase, the chromosomes reach the opposite poles, decondense, and nuclear envelopes reform around each set of chromosomes, creating two nuclei.
Step 4: Compare the options provided in the question (Anaphase, Metaphase, Prophase) with the description of telophase. None of the other stages represent the final step of mitosis.
Step 5: Conclude that telophase is the correct answer because it is the last stage of mitosis, marking the completion of nuclear division before cytokinesis occurs.
