Question

In a cell cycle, which of these phases has the shortest duration?

• A. Interphase
• B. S phase
• C. M phase (Mitosis phase)
• D. G phase

Answer 1

The correct option is C

M phase (Mitosis phase)

It is significant to note that 24 hours is the average duration of the human cell cycle. Out of those 24 hours, the Mitotic phase is the shortest phase that lasts for only about an hour. The interphase lasts more than 95% of the duration of the cell cycle. Interphase includes $G_1$, S, $G_2$ phases.
