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

Text Solution

AI Generated Solution

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 is the series of events that take place in a cell leading to its division and replication. It is divided into two main phases: Interphase and M-phase (Mitosis). 2. **Duration of the Cell Cycle**: The average duration of the entire cell cycle for a mammalian cell is approximately **24 hours**. 3. **Phases of the Cell Cycle**: - **Interphase**: This is the preparatory phase where the cell prepares for division. It consists of three sub-phases: ...
