Question

Which is the longest phase of cell cycle?

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

Answer 1

Answer: (A)

G${}_1$ phase

G${}_1$ phase is also known as the first gap. It is usually the longest period of the cell cycle. However, in some embryonic cells that are rapidly dividing, G${}_1$ might only last a few minutes. It synthesizes mRNA and proteins. So, the correct answer is option A.
