1. G1 Phase (First Gap Phase):
* Growth: The cell increases in size and synthesizes new proteins and organelles.
* Preparation: The cell prepares for DNA replication.
* Checkpoint: The cell checks for sufficient resources and undamaged DNA before moving on to the next phase.
2. S Phase (Synthesis Phase):
* DNA Replication: The cell's DNA is duplicated, ensuring each daughter cell receives a complete copy of the genome.
3. G2 Phase (Second Gap Phase):
* Growth: The cell continues to grow and produce more proteins and organelles.
* Preparation: The cell prepares for mitosis (or meiosis, for reproductive cells).
* Checkpoint: The cell checks for any errors in DNA replication and ensures everything is ready for cell division.
Important Notes:
* G0 Phase: Some cells, like nerve cells, enter a quiescent state called G0 where they exit the cell cycle and don't divide. They may re-enter the cycle later, but many remain in G0 indefinitely.
* Interphase is essential for cell growth, development, and repair. It's the period where the cell performs its normal functions and prepares for the next division.
