Which event occurs during interphase?

• the cytoplasm divides
• centrioles duplicate
• spindle fibers begin to form
• centromeres divide

Cancer affects

• humans only
• unicellular organisms only
• multicellular organisms only
• multicellular and unicellular

Compared to small cells, large cells have more trouble

• dividing
• producing daughter cells
• storing needed materials and waste products
• moving needed materials in and waste products out

Why are stem cells important?

• they have specialized DNA.
• they are incapable of becoming cancer cells
• they have the potential to undergo cell division
• they have the potential to develop into other cell types
