Uncontrolled cell division is stopped by...

• tumor suppressor genes
• oncogenes

Which is an example of a tumor suppressor gene?

• apoptosis
• proto-oncogenes
• p53
• oncogenes

When is apoptosis initiated?

• When DNA damage is repaired.

• When cells are removed from the cell cycle.

• When DNA damage cannot be repaired.

Proto-oncogenes can mutate into...

• oncogenes
• tumor suppressor genes
• DNA repair proteins

Random errors in gene replication that lead to a change in the sequence of DNA

• Mutations

• Cell Cycle Checkpoints

• Mitosis

What is apoptosis?

• The process of cell mutation
• The process of cell division
• The process of programmed cell death
• The process of cell growth

What is the purpose of the cell cycle checkpoints?

• To make sure the cell isn't duplicating too fast

• They were there by chance and happen to help reduce the chances of cancer

• To make sure that all parts of the cell are healthy to avoid mutations

What is osteosarcoma?

• A type of bone cancer
• A type of blood cancer

• A type of ear cancer

• A type of eye cancer

What does metastasis mean?

• The spread of cancer cells from the original site to other parts of the body
• The elimination of cancer cells from the body
• The shrinking of cancer cells at the original site
• The development of cancer cells at the original site

Which is cancer: benign or malignant?

• malignant
• benign
