Question

When a cell stops growing say due to shortage of nutrients, this will occur in which phase of the cell cycle?

• A. $G_1$ phase
• B. S phase
• C. $G_2$ phase
• D. M phase

Answer 1

The correct option is A $G_1$ phase

At the G1 phase of the cell cycle, the cell decides whether the cell will continue to divide or will enter a dormant stage called the G0 stage. If sufficient nutrients are not present the cell will enter this dormant stage of the cell cycle. If however, sufficient growth hormones and proteins are present the cell will continue through the cycle and enter the S phase.

So, the correct answer is option A.
