Question

Which one is the longest phase of cell cycle?

• A. Prophase
• B. Telophase
• C. $G_{1-}$ Phase
• D. $G_{2-}$ Phase

Answer 1

The correct option is C $G_{1-}$ Phase

$G_1$ phase is typically the longest phase of the cell cycle. This can be explained by the fact that G1 follows cell division in mitosis; G1 represents the first chance for new cells have to grow. Cells usually remain in G1 for about 10 hours of the 24 total hours of the cell cycle.
