How does DNA replication relate to the cell cycle?

• DNA replication occurs during the G2 phase
• DNA replication occurs during the G1 phase
• DNA replication occurs during the S phase
• DNA replication occurs during mitosis

Why is cell cycle regulation important in preventing diseases like cancer?

• It ensures proper cell division
• It prevents DNA damage
• It regulates cell metabolism
• It promotes apoptosis

What is the purpose of the G1 phase in the cell cycle?

• To prepare for cell division
• To divide the cytoplasm
• To ensure DNA is undamaged
• To replicate DNA

What is the role of checkpoints in the cell cycle?

• To regulate the cell's metabolism
• To prevent the cell from entering apoptosis
• To ensure the cell has enough energy to divide
• To stop the cell cycle if DNA replication is incomplete
