Lesson 1
Which type of cancer is most commonly diagnosed?
Female breast cancer
In which two phases does the cell add nutrients, proteins, and chromosomes?
G1 and G2
Which type of cancer is most lethal?
Lung and Bronchus cancer
List the levels of organization from smallest to largest
Cells -> Tissues -> Organs -> Organ Systems -> Organism
During which stage of the cell cycle does the cell duplicate its DNA?
S phase
What is the correlation between age and cancer?
Older people are more likely to get cancer
How are cancer cells different from non-cancer cells?
They have a mutation in their chromosomes
What is the gene that protects animals from getting cancer?
How do tumors cause illness?
Tumors disrupt the normal functions of the body
What is p53's role in the cell cycle?
p53 regulates the cell cycle - it makes sure the cell has enough materials to divide.
Why do taller people have higher rates of cancer?
Taller people have more cells, which lead to more mutations.
Large animals rarely get cancer. What protects them from getting cancer?
How do non-cancer cells form from the cell cycle?
p53 fails to regulate cell division, leading to non-cancer cells becoming cancer cells.
Why do older people have higher rates of cancer?
Their cells have divided more, which leads to more mutations.
