In a typical 24-hour cell cycle of a human cell, approximately how long does the actual M phase (mitosis) last?
Show answer and explanation
Correct answer: 1 hour
Interphase lasts for more than 95% of the duration of the cell cycle. In a 24-hour cycle, the M phase typically lasts for only about one hour.
