Apoptosis and Cancer

What is Apoptosis?

• Cell programmed Death

• Inflammation of cell

• Phagocytosis

• Necrosis

Give the correct sequence of apoptosis:

1. Nucleus begins to break

2. Nucleus condensation and formation of bleb

3. Phagocytosis of apoptotic bodies.

• 1, 2, 3

• 2, 3, 1

• 3, 2, 1

• 2,1,3

What could be the cause for a cell to undergo apoptosis?

• DNA Damage

• Nutrient deficiency

• Radiation

• All of the above

Cancer creates abnormal cells by disrupting

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

What enzyme do some cells have that can increase the length of telomeres?

• DNA polymerase

• RNA polymerase

• DNase

• telomerase

Which type of cells actively produce telomerase? (select 2)

• Adult Stem Cells

• Cancer Cells

• Embryonic Stem Cells

• Adult Somatic Cells

Cellular "old age" or the point at which a mature cell will no longer divide is called

• apoptosis

• differentiation

• redifferentiation

• senescence

Programmed cell death is called

• apoptosis

• differentiation

• telophase

• senescence

Which is NOT a characteristic of a cancer cell?

• active telomerase

• telomeres that can lengthen

• responds to an apoptotic signal

• cannot respond to an apoptotic signal
