Question

Of the four different phases of mitotic cell cycle, usually the phase with the shortest duration is the __________.

• A. $G_1$
• B. S
• C. $G_2$
• D. M

Answer 1

The correct option is D M

There are four stages in the cell cycle. The interphase is comprised of G1, S and G2 phase. The M phase is considered as the shortest phase in the cell cycle. About 80% of the time is required in the interphase and only 20% in the M-phase. In the M-phase, the shortest phase is anaphase which takes about 0.8% of the cell cycle.

So, the correct option is 'D'.
