G1, S, G2 are the steps of...

• Cytokinesis

• Prophase

• Mitosis

• Interphase

Tags

NGSS.HS-LS4-2

What is the purpose of the cell cycle checkpoints?

• To make sure the cell isn't duplicating too fast

• They were there by chance and happen to help reduce the chances of cancer

• To make sure that all parts of the cell are healthy to avoid mutations
