What is the average cell cycle span for a mammalian cell?

Explanation

To determine the average cell cycle span for a mammalian cell, we can break down the information as follows:

1. **Understanding the Cell Cycle**: The cell cycle consists of several phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). Each phase has a specific duration.

2. **Average Duration**: The average cell cycle span for a mammalian cell is approximately **24 hours**. This is a general estimate and can vary slightly depending on the specific type of mammalian cell.

3. **G1 Phase Duration**: Within this 24-hour cycle, the G1 phase typically lasts about **10 hours**. This is the phase where the cell grows and prepares for DNA synthesis.
