Biotech and Cancer

Question 1

Cancer

Answer 1

A disease caused by an uncontrolled division of abnormal cells in a part of the body. A malignant tumor from the division of abnormal cells

Question 2

Progeny

Answer 2

Offspring from sexual reproduction

Question 3

Tumor supressor genes

Answer 3

AKA anticogene and it protects the cell from one step on the path to cancer. When it mutates, it causes the cell to progress to cancer.

Question 4

Genome

Answer 4

A complete set of an organisms genes; an organism’s genetic material

Question 5

Metastasize/Malignant

Answer 5

-Spread through circulation-A tumor that spreads into neighboring tissues and other parts of the body. Separates from the original tumor or secretes signals to cause blood vessels of circulatory system and cancer cells spread through the circulatory system (Metastasis).

Question 6

Apoptosis

Answer 6

Cell death/suicide

Question 7

Oncogenes

Answer 7

-A gene that is a mutated/changed form of a involved in normal cell growth and may cause cancer.

Question 8

Pathology

Answer 8

-The study of pathogens (agents like a virus,bacteria, or fungus that causes disease).

Question 9

Cyclin

Answer 9

Moves cell from G1 to Mitosis. A checking protein.-Checkpoint

Question 10

Angiogenesis

Answer 10

-The development of new blood vessels

Question 11

p53

Answer 11

Prevents cells from completing mitosis cycle if the DNA or other parts of the cell are damaged. If the damage is minor, then the progress is halted until repairs are completed or if the damage cannot be repaired, then p53 triggers apoptosis. A checking protein.-Checkpoint

Question 12

Biotechnology def

Answer 12

The manipulation of organisms or components to make useful products

Question 13

Link between cancer and mitosis

Answer 13

Cancer is caused from uncontrolled mitosis/is uncontrolled mitosis and it doesn’t follow the checkpoints of mitosis.They divide very often and grow into tumors

Question 14

Factors that influence cancer

Answer 14

-Genetics-Excessive exposure to UV light-Diet-Tobacco-Obesity-Hormones-Radiation

Question 15

How is cancer diagnosed

Answer 15

Test tissue sample and compare it to normal tissue

Question 16

What does an oncologist do

Answer 16

Evaluates and treats people with cancer

Question 17

What does a histologist do

Answer 17

Look at tissues under a microscope and evaluate them to see if the person has cancer or not

Question 18

Back up systems that help cells avoid proliferation

Answer 18

• Edit DNA -> crispr
• DNA polymerase repairs
• Telomeres hold the DNA from unraveling and mutating
• Apoptosis -> kill themselves before bad replication

Question 19

Histology

Answer 19

-The study of tisses

Question 20

Markers

Answer 20

Specific sequences within a gene, genetic markers

Question 21

Telomeric ends

Answer 21

Aglet, holds DNA from unraveling

-Keeps your cell intact
