7

Other Answer Choices:

G0 - cell doing "job", but not dividing

Cytokinesis - dividing the cell parts and splitting the cell into 2 daughter cells

M phase - mitosis AND cytokinesis

G2 - Gap 2 - cell is preparing for cell division

Mitosis - moving and separating chromosomes

Identify the 4 checkpoints of the cell cycle

Other Answer Choices:

S Check Point - is all the DNA duplicated?

G1 Check Point - leave cell cycle to "do job" or commit to divide?

G2 Check Point - is DNA all duplicate correctly and no damage?

M Check Point - are all chromosomes lined up correctly at metaphase?

PROCESSING NUTRIENTS		Superpower of Cancer - cancer cells break free from original tumor and travel through the body to create new tumors in different areas of the body
GROWING UNCONTROLLABLY		Superpower of Cancer - that allows cells to divide more quickly than normal cells
AVOIDING DETECTION		Superpower of Cancer - where cell is able to keep the tips of its chromosomes (telomeres) LONG so that cell can continue to divide FOREVER
EVADING DEATH		Superpower of Cancer - where because cells have acquired some mutations become unstable which then lead to even more mutations (and more superpowers)
INVADING TISSUES		Superpower of Cancer - where cells are able to create and send signals for blood vessels to grow into the tumor so tumor can continue to grow
PROMOTING MUTATIONS		Superpower of Cancer - Cancer cells must avoid detection by the B cells and T cells of the immune system. These cells destroy emerging pre-cancerous cells are normally eliminated by the immune response.
BECOMING IMMORTAL		SUPERPOWER OF CANCER - Cancers cells do not undergo apoptosis (commit PROGRAMMED CELL DEATH) EVEN when they are damaged.

What is the job of a "normal" proto-oncogene (not the mutated oncogene)?

What is the job of a "normal" tumor suppressor gene (not a mutated tumor suppressor gene)?

Which description(s) of how mutations in genes cause cancer is/are correct?

Unfortunately most risk factors for cancer are not in an individual's control therefore there is not much any one person can do to lower their risk for cancer

Explain how cancer cells "get" superpowers?

Explain what happened in our Cancer Cell Survival Challenge... What happened to MOST or ALL of the cancer cells? WHY?

Explain what happened in our Cancer Cell Survival Challenge... What DID allow (or would have allowed) one or more cancer cells to survive? WHY?

If a cancer cell acquired several "superpowers" from mutations that created oncogenes and mutations that "broke" tumor suppressor genes, what could happen to the 4 checkpoints of the cell cycle? Explain.

Draggable item		Corresponding Item
Hormone Therapy		A testing method that helps doctors analyze your cancer and choose the most effective treatment plan based on specific features of your cancer cells.
Biomarker Testing for Cancer Treatment		This type of treatment works by using powerful medicines to kill fast-growing cells in the body, including cancer cells.
Blood Stem Cell Transplant		This treatment works by stopping or slowing down cancers that depend on certain hormones to grow, particularly in breast and prostate cancers.
Radiation Therapy		This treatment uses your body's own natural defenses to help fight cancer cells. It works by boosting your immune system's ability to attack cancer.
Cancer Surgery		This treatment uses special drugs that become activated when exposed to light, destroying cancer cells and other abnormal cells in the body.
Photodynamic Therapy		This type of therapy uses high-energy waves or particles to destroy or damage cancer cells, making tumors smaller.
Chemotherapy		This procedure involves removing blood-forming stem cells, storing them, and returning them to the body after high-dose cancer treatments have been completed.
Immunotherapy		Procedure where a surgeon identifies and cuts out/removes a tumor(s) from the patient's body
Targeted Therapy		This treatment specifically blocks cancer growth by targeting particular changes in cancer cells that help them grow and spread.

Superpower of Cancer - where cell is able to keep the tips of its chromosomes (telomeres) LONG so that cell can continue to divide FOREVER

PROMOTING MUTATIONS

Superpower of Cancer - Cancer cells must avoid detection by the B cells and T cells of the immune system.  These cells destroy emerging pre-cancerous cells are normally eliminated by the immune response.

BECOMING IMMORTAL

SUPERPOWER OF CANCER - Cancers cells do not undergo apoptosis (commit PROGRAMMED CELL DEATH) EVEN when they are damaged.

Proto-oncogenes mutate to become oncogenes which act to push the cell through cell division (like getting accelerator stuck to the floor of the car)

Most cancers need 5-7 DNA mutations to develop

Mutations to create oncogenes or break tumor suppressor genes give the cancer cell superpowers (hallmarks)
