What does the p53 gene do in cell division?

• It duplicates chromosomes.

• It accelerates cell division.

• It regulates cell division at checkpoints.

• It destroys cancer cells.

What happens if p53 doesn't control cell division?

• Non-cancer cells may form cancer cells.

• Cells become part of tissues.

• Cells stop dividing.

• Cells duplicate their chromosomes.

What is the link between height and cancer rates?

• Height is not linked to cancer rates.

• Shorter people have higher cancer rates.

• Height reduces cancer risk.

• Taller people have higher cancer rates.

What is a characteristic of cancer cells?

• They do not stick together.

• They do not form tumors.

• They can invade tissues and disrupt systems.

• They look the same as non-cancer cells.

What does p53 do during DNA replication?

• It forms new cells.

• It corrects errors.

• It accelerates mutations.

• It duplicates chromosomes.

What is a common feature of all cells?

• They are all cancerous.

• They all have different chromosomes.

• They are part of a hierarchical system.

• They do not divide.

What is the link between age and cancer rates?

• Older people have higher cancer rates.

• Younger people have higher cancer rates.

• Age decreases the chance of cancer.

• Age is not associated with cancer rates.
