Diagram labels and functions
| Structure / stage | Function |
|---|---|
| G1 phase | Cell grows and makes proteins. |
| S phase | DNA is replicated. |
| G2 phase | Cell checks DNA and prepares for division. |
| M phase | Mitosis and cytokinesis produce daughter cells. |
| G0 phase | Optional non-dividing state. |
How to read the cell cycle diagram
Interphase contains G1, S and G2. M phase then separates the copied chromosomes and divides the cytoplasm before the cycle begins again.
Why checkpoints matter
Checkpoints pause the cycle if DNA is damaged, replication is incomplete or chromosomes are not correctly attached to the spindle.

When is DNA copied?
During S phase of interphase.
What happens in M phase?
