Cell Cycle and Cancer Cell Concepts

What is the main purpose of the cell cycle?

• To make food for the cell

• To help the cell grow and divide

• To allow the cell to move around

• To store energy for the cell

What two main things are chromosomes made of?

• Sugar and water

• Fats and carbohydrates

• DNA and proteins

• Vitamins and minerals

What important process happens during the S phase of the cell cycle?

• The cell grows larger

• The cell divides into two new cells

• The cell's DNA is copied

• The cell rests and does nothing

Which type of cells in the human body typically do not divide?

• Skin cells

• Liver cells

• Blood cells

• Nerve cells

What two main types of proteins help control the cell cycle?

• DNA and RNA

• Protein kinase and cyclin

• Enzymes and hormones

• Receptors and signals

What does the G1 checkpoint decide for a cell?

• If DNA replication happened correctly.

• If the cell is ready to divide.

• If the cell will divide or enter a resting state.

• If chromosomes are attached to spindles.

What happens to a cell if it enters the G0 phase?

• It starts dividing rapidly.

• It becomes a cancer cell.

• It stops dividing and enters a resting state.

• It immediately moves to the M phase.

What is a main problem with cancer cells?

• They divide too slowly.

• They stop dividing when there's no room.

• They divide out of control.

• They always have normal DNA.
