1
Q

Genetics

A

The science that accounts for natural differences and resemblances among organisms related by descent

2
Q

heredity

A

the process by which organisms pass genetic traits on to their offspring

3
Q

DNA

A

The combination of proteins, called nucleotides, that arranged to make up an organism’s chromosomes

4
Q

Human Genome Project

A
  • funded by the US government and was started in 1990 to analyze the human body
  • mapping of all the genes within the 23 pairs of human chromosomes
  • the project finished early.
5
Q

Types of Genetic testing

A
  • predictive
  • carrier
  • prenatal
  • preimplantation
  • forensics
6
Q

Predictive testing

A

a test used to see if genes are present that could lead to hereditary disease or other harmful genetic conditions.

7
Q

Prenatal testing

A

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

8
Q

chromosome

A

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

9
Q

gene

A

a tiny segment of DNA found on a chromosome within a cell’s nucleus. It holds the formula for making a specific enzyme or protein.

10
Q

genome

A

all the DNA in an organism, including its genes.

11
Q

Forensic testing

A

a test used in law enforcement to eliminate or designate suspects in a crime, identify homicide victims, or to otherwise analyses DNA samples for law enforcement purposes

12
Q

Mutations

A

a permanent change in the DNA

13
Q

amniocentesis

A

a test where by the fluid is tested for genetic or other conditions that may lead to abnormal development of the fetus.

14
Q

genetic counselor

A

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

15
Q

genetic discrimination

A

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

16
Q

genetic engineering

A

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

17
Q

clone

A

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

18
Q

cloning

A

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

19
Q

xenotransplantation

A

transplantation of animal tissues and organs into humans

20
Q

Objections to animal cloning

A
  • does not always yield viable offspring
  • 30% are affected with large offspring syndrome
  • premature death
21
Q

stem cells

A

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

22
Q

multipotent stem cells

A

stem cells that can become a limited number of types of tissues and cells in the body

23
Q

pluripotent stem cells

A

stem cells that can become almost all types of tissues and cells in the body

24
Q

gene therapy

A

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

25
Q

infertility

A

the failure to conceive for a period of 12 months or longer due to a deviation from or interruption of the normal structure or function of any reproductive part organ or system

26
Q

in vitro fertilization (IVF)

A

fertilization that takes place outside a woman’s body literally “in glass” as in a test tube

27
Q

artificial insemination

A

the mechanical injection of viable semen into the vagina

28
Q

homologous artificial insemination

A

the process in which a husband’s sperm is mechanically injected into his wife’s vagina to fertilize her eggs.

29
Q

surrogate mother

A

a woman who becomes pregnant, usually by artificial insemination or surgical implantation of a fertilized egg, and bears a child for another woman

30
Q

heterologous artificial insemination

A

the process in which donor sperm is mechanically injected into a woman’s vagina to fertilize her eggs

31
Q

parens patriae

A

a legal doctrine that gives the state the authority to act in a child’s best interest

32
Q

Best interest of the child

A

The standard that best safeguards the child’s growth, development and health

33
Q

conditions were physicians may hold medical treatment

A
  • chronically irreversibly comatose
  • will most certainly die and for whom treatment is considered futile
  • would suffer inhumanely if treatment were provided
34
Q

safe heaven laws

A

state laws that allow mothers to abandon newborns to designated safe facilities without penalty

35
