Posted September 16, 2022
Answer
The M phase is the shortest phase of a cell cycle. Also known as the mitotic phase, it occurs over a period of 2 hours.
The cell cycle consists of 4 main phases, which occur over a period of 24 hours.
The G1 phase is the longest, with a duration of about 11 hours.
The S phase is the second longest. It lasts for about 7 hours.
The G2 phase lasts for 4 hours.
The M phase is the shortest, with a duration of only about 2 hours.
