Question

Cell division can not be stopped in which phase of the cell cycle?

• A. G${}_1$ phase
• B. G${}_2$ phase
• C. S phase
• D. All of the above

Answer 1

Answer: (C)

S phase

A cell in G${}_1$ phase has three options, Continue division cycle and enter S phase, exit normal cell cycle and enter G${}_o$ phase, stop cell cycle and undergo differentiation. S phase is the synthesis phase which is marked with DNA replication. Once DNA gets replicated the cell division cannot be stopped.

So, the correct answer is option C.
