Review: Check-In #1

What is the purpose of the cell cycle?

• To ensure growth, repair, and reproduction of cells
• To control the body's temperature
• To produce energy for the cell
• To regulate the immune system

Cells spend most of their time in what stage of the cell cycle?

• Interphase (includes G1, S, and G2 phase)

• Metaphase

• Anaphase

• None of the above

Skin color is produced by cells called

• Melanin

• Melanocytes

• Epidermal Cells

• Cytokinesis Cells

During the G1 of the cell cycle, the cell

• grows by collecting nutrients

• makes a clone of itself

• makes more DNA

• grows more in preparation for mitosis

If a cell reaches a checkpoint and has an issue that CAN be fixed, what happens?

• The cell pauses and is repaired

• The cell goes into programmed cell death (apoptosis)

• The cell divides

• The cell gets bigger

If a cell reaches a checkpoint and has an issue that CANNOT be fixed, what happens?

• The cell goes into programmed cell death (apoptosis)

• The cell grows more

• The cell divides

• The cell creates more DNA

Melanoma can come in all shapes and forms, such as: (select all that apply)

• Cysts

• Bruises

• Moles

• Hair follicle

If you have contact with someone who has cancer, is it likely that it will spread to your body?

• Yes, because cancer is contagious

• No, because cancer is not contagious

The function of checkpoints in the cell cycle is to

• Check to make sure that a cell is ready and healthy to move into the next phase

• Check to make sure the cell has an appropriate color

• Check to make sure the cell has gathered organelles from a random cell

• Check to make sure the cell has a good music taste

Jason went to the doctor, who told him he had a benign tumor. Will his benign tumor grow back?

• Yes, because benign tumors always grow back.

• No, because benign tumors do not grow back once removed.
