Cell Cycle and Mitosis
The cell cycle is a series of events that occur in a cell as it grows and divides. Mitosis is the process by which a cell divides into two identical daughter cells.
Here is a summary of the cell cycle:
- G1 phase: The cell grows and prepares for DNA replication.
- S phase: DNA is replicated.
- G2 phase: The cell prepares for mitosis.
- M phase: Mitosis occurs.
