Week 8: Vocab

Question 1

Angiogenesis

Answer 1

successful tumors secrete chemical signals that cause blood vessels to sporut from the circulatory system - results in heavy cells receiving less oxygen and good molecules

Question 2

Answer 2

A disease of uncontrolled cell proliferation

Question 3

Colonoscopy

Answer 3

A procedure used to examine the large intestine, rectum, and anus to screen men and women for colon or rectal cancer

Question 4

Growth Inhibitor

Answer 4

A signal molecule that prevents cell division

Question 5

Immunotherapy

Answer 5

patient’s immune system is used to fight cancer

Question 6

Oncogene

Answer 6

A gene that tells the cell to divide in the absence of normal instructions to do so

Question 7

Transcription Factor

Answer 7

A molecule that regulates which genes are active in a cell

Question 8

Apoptosis

Answer 8

Cell Death

Question 9

Cell Cycle

Answer 9

4 distinct phases of cell life: mitosis (the chromosomes separate into daughter cells), Gap 1 (the cell grows), DNA synthesis (the chromosomes replicate), and Gap 2 (the cell grows and prepares again for mitosis)

Question 10

A fluid-filled sac

Question 11

Melanoma

Answer 11

An invasive and deadly skin cancer

Question 12

Malignant

Answer 12

cell growth that continues in an uncontrolled manner, resulting in cancer

Question 13

Proto-Oncogene

Answer 13

A gene that encodes for a protein that regulates cell division

Question 14

Tumor

Answer 14

A lump that results from the production of extra cells

Question 15

Benign

Answer 15

Harmless, doesn’t grow or spread

Question 16

Chemotherapy

Answer 16

Generally used to treat cancers that have spread from the primary tumor

Uses drugs that impair the ability of cells to replicate

Question 17

Growth Factor

Answer 17

Many normal cells require signal molecules that are called growth factors in order to grow.

Question 18

Human Papillomavirus (HPV)

Answer 18

is responsible for the world’s cancers of the genitals and anus

Its a sexually transmitted disease

Question 19

Metastasis

Answer 19

A process by which individual cancer cells leave a tumor, enter the bloodstream, and produce secondary tumors at new sites

Question 20

Signal Transducer

Answer 20

A molecule inside the cell that relays the information once a signal molecule binds to a receptor

Question 21

Tumor Supressor

Answer 21

A gene that encodes for a protein that tells a cell not to divide
