Cancer & Cell Cycle Practice

Programmed cell death is called

• Metastasis

• Monosomy

• Apoptosis

• Macrophagey

Which of the following best defines cancerous cells?

• Unregulated cell growth

• Incapable of creating new DNA

• Lack of mitochondria

• Slow cell replication

Cells that "leave" the cell cycle and no longer replicate are considered to be in the ____ phase.

• N0

• G0

• M

• Passive

Which of the following provides a natural sunscreen for skin?

• melanin

• carotene

• hemoglobin

• vitamin D

Cancer creates abnormal cells by disrupting

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

Tumor suppressing genes code for:

• Inhibiting proteins

• Stimulating proteins

Cancer can be described as

• cells that undergo apoptosis - programmed cell death

• cells that undergo unregulated growth and division

• cells that remain in interphase

• cells that do NOT have mutations in their cyclins

Which of these cell samples is more likely to be cancer? Look at the table carefully!

• Lung Tissue Sample 1 because there are more cells in interphase

• Lung Tissue Sample 2 because there are more cells in mitosis (cell division)

• Lung Tissue Sample 1 because there are more cells in mitosis (cell division)

• Lung Tissue Sample 2 because there are more cells in interphase

Which of these cell samples is more likely to be cancer? Look at the table carefully!

• Ovary Tissue Sample 1 because there are more cells in interphase

• Ovary Tissue Sample 2 because there are more cells in mitosis (cell division)

• Ovary Tissue Sample 1 because there are more cells in mitosis (cell division)

• Ovary Tissue Sample 2 because there are more cells in interphase

A student is studying two samples of cells. She tracks their growth and division over time and creates the following graph. Which sample is most likely to be cancer?

• Sample A because they are showing rapid growth and division

• Sample B because they are showing rapid growth and division

• Sample A because they are not dividing very rapidly

• Sample B because they are not dividing very rapidly
