Gene Expression and Cancer

What is the usual function of tumor suppressor genes?

• Promote cell growth and division

• Inhibit cell growth and division

• Regulate cell movement

• Control cell metabolism

How does understanding genetic changes help scientists?

• By developing ways to fix or regulate cell growth

• By creating new species of organisms

• By studying the behavior of stars and galaxies

• By exploring the depths of the ocean

What is gene expression similar to?

• Cooking a recipe

• Following a map

• Reading a book

• Listening to music

How can mutations in genes affect cell growth and division?

• By promoting abnormal cell growth

• By inhibiting cell division

• By disrupting the normal dance of cell growth and division

• By enhancing the process of cell differentiation

What happens when proto-oncogenes are mutated?

• They become less active

• They encourage cell growth and division

• They become dormant

• They have no effect on cell growth

What is the role of gene regulation in cell growth?

• Controlling the dance of cell growth

• Causing disruptions in cell growth

• Preventing cell growth

• Having no impact on cell growth

What can play a role in the development of cancer?

• Vaccines

• Mutations

• Exercise

• Diet
