What is the cell cycle?

• The process of cell division

• The growth and replication of cells

• The formation of body tissues

• The regulation of cell functions

• To form body tissues

• To divide cells and make more cells

• To control the growth of multicellular organisms

Why is cell division important for growth?

• To increase the size of individual cells

• To regulate cell functions

• To form body tissues

• To make more cells in multicellular organisms

What happens when cells divide too frequently?

• They become uncontrolled and may develop into cancer cells

• They communicate better with other healthy cells

• They carry out normal cell functions more efficiently

• They securely anchor themselves like other cells

What are some problems that cancer cells may have?

• Inability to communicate with other healthy cells

• Inability to carry out normal cell functions

• Inability to securely anchor themselves

• All of the above

What can cause cells to become cancerous?

• Genetic factors

• Exposure to toxins

• Excessive exposure to UV light

• All of the above

What is the role of the cell cycle checkpoints?

• 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

• It replicates its DNA incorrectly

What are positive regulators of the cell cycle?

• Cyclin and Cdk

• p53 protein

• Genetic factors

• Exposure to toxins
