What is the basic sequence of the mitosis process?

• A. Chromosomes duplicate, cell splits
• B. DNA copies, cell grows
• C. Nucleus dissolves, spindle forms
• D. Cytokinesis occurs first

Answer: (A)

The basic sequence being tested is that genetic material must be prepared before division, then the cell splits to form two cells. Chromosomes duplicate during the preceding cell cycle so each chromosome has two sister chromatids to separate later. After this preparation, the nucleus divides (mitosis) and, finally, the cytoplasm divides (cytokinesis) to yield two distinct daughter cells. So describing chromosomes duplicating and then the cell splitting captures the core flow: replication before division, followed by the division into two cells. The other options mix up the timing or omit steps: DNA copying and growth happen earlier in the cycle, prophase events like the nucleus dissolving and spindle formation are parts of mitosis but don’t describe the overall sequence, and cytokinesis occurring first would mean the cell splits before the nucleus divides, which isn’t correct.
