What is the cell cycle?

• The process of cell division

• The growth and replication of cells

• The regulation of cell functions

• The formation of body tissues

What is mitosis?

• The splitting of the cytoplasm

• The replication of DNA

• The growth of individual cells

• The division of cells to make more cells

Why is cell division regulated?

• To prevent cells from growing too big

• To ensure cells can communicate with each other

• To carry out normal cell functions

• To prevent uncontrolled cell growth and cancer

What is cancer?

• A disease caused by uncontrolled cell division

• A genetic disorder that runs in families

• A condition where cells cannot communicate with each other

• A process of cell growth and replication

What is the purpose of checkpoints in the cell cycle?

• To check if the cell is growing well enough

• To check if the DNA is damaged

• To check if the cell has the resources it needs

• All of the above

What happens if a cell doesn't meet the requirements of a checkpoint?

• It pauses until the issue is fixed

• It continues to the next phase of the cell cycle

• It undergoes apoptosis and self-destructs

• It becomes a cancer cell

What proteins are involved in regulating the cell cycle?

• Cyclin and Cdk

• p53 and Cdk

• Cyclin and p53

• Cdk and p53
