Question

Which among the following is the longest phase of cell cycle?

• A. Prophase
• B. Telophase
• C. G${}_1$
• D. G${}_2$

Answer 1

The correct option is C G${}_1$

The cell cycle is an ordered set of events, culminating in cell growth and division into two daughter cells. The stage is G${}_1$-S-G${}_2$-M. Protein and RNA are synthesized during G${}_1$ phase which is used for DNA synthesis in the S phase.Therefore, the longest phase is the G${}_1$ phase and lasts for about 11 hrs in a cycle that is completed in 24 hrs.

So, the correct answer is option A.
