Question 7

Prenatal testing

Answer 7

a test used to see, through a process called amniocentesis, if harmful genes are present in the fetus

chromosome

Answer 8

a microscopic structure found within the nucleus of all living cells that carries genes responsible for the organism’s characteristics

an expert in human genetics who is qualified to counsel individuals who may have inherited genes for certain diseases or conditions.

Question 15

genetic discrimination

Answer 15

differential treatment of individuals based on their actual or presumed genetic differences

Question 16

genetic engineering

Answer 16

manipulation of DNA within the cells of plants, animals and other organism’s through synthesis, alteration or repair to ensure that certain harmful traits will be eliminated in offspring and that desirable traits will appear and be passed on

Question 17

clone

Answer 17

an organism produced asexually, usually from a single cell of the parent

Question 18

cloning

Answer 18

the process by which organisms are created asexually, usually from a single cell of the parent organism

Question 19

xenotransplantation

Answer 19

transplantation of animal tissues and organs into humans

Question 20

Objections to animal cloning

Answer 20

• does not always yield viable offspring
• 30% are affected with large offspring syndrome
• premature death

Question 21

stem cells

Answer 21

cells that have the potential to become any type of body cell

gene therapy

Answer 24

treating harmful genetic diseases or traits by eliminating or modifying the harmful gene
