During interphase, a cell grows, duplicates organelles, and

• Divides the nucleus

• Doubles its DNA

• Divides the cytoplasm

• Produces a new cell

Why do multicellular organisms undergo mitosis?

• To create reproductive cells for having offspring

• To create mutations within an organism

• Producing new and uniquely different cells

• To produce cells that are identical to the original cell

One difference between a cancer cell and a normal cell is that

• Cancer cells divide uncontrollably

• Normal cells divide uncontrollably

• Cancer cells cannot make copies of DNA

• Normal cells cannot make copies of DNA

If a cell does not go through the S phase of the cell cycle before mitosis, what might be wrong with the daughter cells?

• They would not have enough mitochondria

• They would have too many mitochondria

• They would not have enough DNA

• They would have too much DNA

What are TWO purposes of the cell cycle?

• For a multicellular organism to grow

• For a multicellular organism to repair damage

• For a multicellular organism to consume ATP

• For a multicellular organism to synthesize proteins

If a cell passes the G1 checkpoint, because there is available space surrounding it, it will

• replicate its DNA and prepare to divide

• Move directly into mitosis

• Remain in G1 and never divide

• Complete cytokinesis

This is the shortest part of the cell cycle, where healthy cells should only spend about 9-10% of their time

• G1

• S

• G2

• M

Recent research has indicated that cancer cells

• Always develop into a malignant tumor

• Pass through cell cycle checkpoints too quickly because of mutations

• Enter the G1 phase at least 3 times before they divide

• Are unable to complete the cell cycle after the S phase
