Step 1: Understand the stages of mitosis and their order. Mitosis is a process of cell division that ensures equal distribution of chromosomes to daughter cells. The main stages are Prophase, Metaphase, Anaphase, and Telophase.
Step 2: Recall what happens in each stage: In Prophase, chromosomes condense and the mitotic spindle begins to form. In Metaphase, chromosomes align at the cell's equatorial plate. In Anaphase, sister chromatids separate and move toward opposite poles. In Telophase, nuclear membranes reform around the separated chromatids, now called chromosomes.
Step 3: Use the sequence of events to determine the correct order. Since chromosomes condense first, Prophase must come first. Then chromosomes align in Metaphase, followed by separation in Anaphase, and finally nuclear reformation in Telophase.
Step 4: Compare the given options with the correct sequence: Prophase → Metaphase → Anaphase → Telophase. Identify which option matches this order exactly.
Step 5: Conclude that the correct sequence of mitosis stages (excluding cytokinesis) is Prophase → Metaphase → Anaphase → Telophase.
