Quiz: Cancer and Mitosis

Question 1

What do Erythrocytes Cells (Red Blood Cells) do?

Answer 1

Carry oxygen to deliver to cells so they can complete cell respiration and make ATP

Question 2

What are Chromosomes?

Answer 2

Organized strands of DNA coiled around histones (proteins

Question 3

What is Interphase?

Answer 3

Cells are just doing their thing and making a copy of their DNA. G1, S, G2

Question 4

What is Prophase?

Answer 4

DNA becomes visible, centrioles form spindle fibers, nuclear membrane begins to dissolve

Question 5

What is Metaphase?

Answer 5

Chromosomes line up in the middle and spindle fibers attach to centromeres on each end of cell

Question 6

What is Anaphase?

Answer 6

Spindle fibers pull chromosomes to either end of the cell

Question 7

What is Telophase?

Answer 7

Spindle fibers dissolve and nuclear membranes begin to form around separate groups of chromosomes

Question 8

What is Cytokinesis?

Answer 8

New cellular membranes separate the new cells. Chromosomes unwind so DNA can do its job making proteins to run the cell

Question 9

What is p53?

Answer 9

Protein that controls cell growth; Cancer antigen-prevents uncontrolled growth; Focus of much research

Question 10

How many cells do we get per day?

Answer 10

100 billion new cells/day

Question 11

What is a Carcinogen?

Answer 11

-a toxin or environmental condition that causes a cell mutation making it unable to commit apoptosis -virus -radiation -chemical

Question 12

What is a Tumor?

Answer 12

A neoplasm that is large enough to form a noticeable lump of differentiated tissue

Question 13

What is a Benign?

Answer 13

A Tumor that is changing very slowly and is not causing immediate medical problems

Question 14

What is a Invasive Tumor?

Answer 14

Fast growing tumor that is causing damage to surrounding tissues. May metastasize and move to other parts of the body

Question 15

What is a HeLa cell?

Answer 15

a cell type in an immortal cell line used in scientific research; It is the oldest and most commonly used human cell line

Question 16

What is the difference between a cancerous cell and a normal cell?

Answer 16

Normal Cells: Have DNA in their genes and chromosomes that functions normally; Divide in an orderly way to produce more cells only when the body needs them Cancer Cells: Develop an aberrant DNA or gene structure or acquire abnormal numbers of chromosomes; Continue to be created without control or order. Excess cells form a mass of tissue called a tumor

Question 17

Why doesn’t Leukemia affect RBC?

Answer 17

RBC’s do not reproduce and are produced in the bone marrow, where stem cells are signaled to turn into a RBC White blood cells like neutrophils are also produced in the bone marrow as well, but from a multi-divisional process

Question 18

What is Apoptosis?

Answer 18

The death of cells that occurs as a normal and controlled part of an organism’s growth or development
