7th Grade Cancer cell

What role do oncogenes play in cancer development?

• They suppress tumor growth

• They start cell death

• They start cell division

• They repair damaged DNA

Which of the following is a common characteristic of cancer cells?

• Cells are NOT identical to each other

• Uncontrolled cell growth

• Normal cell cycle

• Programmed cell death

• Cells are identical to each other

What is the primary role of tumor suppressor genes in mitosis

• Encouraging tumor growth

• Stopping cell division (mitosis), and preventing cancerous cells from spreading

• Enhancing the immune system's ability to attack tumors

• Promoting the mutation of cancer cells

Cancer cells are continually dividing. Because of this drugs used to treat cancer stop

• photosynthesis

• transcription

• mitosis (cell division)

• cellular respiration

Cell cycle checkpoints are able to stop mutated cells. Mutated cells are cancerous. If the checkpoints are damaged, they are unable destroy (stop) cancerous cells from dividing. Compared to normal cell division,

• cancer cell cycle is faster

• cancer cell cycle is uncontrollable

• cancer cell is continous

• all of the above

Cancer is

• a premature stop in the cell cycle.
• uncontrolled mitosis.
• programmed cell death.

Cancer creates abnormal cells by disrupting

• the cell cycle
• red blood cell formation
• DNA replication
• ATP synthesis

An abnormal mass of cancer cells is called a 

• tumor
• cyst
• lesion
• polyp

Define Metastasis

• When cancer reaches to other parts of the body

• Cancer that is treated by medicine

• Cell Death
