Q

Genes

Study These Flashcards
A

molecules of DNA,

23
Q

DNA

Study These Flashcards
A

4 chemicals 1. adenine, 2 thymine, c. guanine, d. cytosine, strands wrapped around (double helix) in every cell in form of genes, sequence est traits

24
Q

what are the genetic bases for individuality?

Study These Flashcards
A

characteristics can be due to 1. one specific gene, 2. sequential arangement of molecules on each gene, 3. particular pair of genes, 4. group of genes interacting with each other, 5 influence of environment on genes.

25
What is an expressed trait
individual manifests the trait
26
What are unexpressed traits
ind is predisposed to trait under certain situations, carrier, can be passed to children who may manifest the trait
27
What is a genetic disorder
disorder resulting from ind genetic makeup, can be present from birth as Developmental disorder, or appear later as health problem
28
What is a single-gene disorder?
absence or alteration of one gene specific to that trait, test avail for many, Cystic Fibrosis, hemophilia, R/G color blindeness
29
What is a multifactoral disorder?
dis. Involves variations of several genes. Harder to dtect bc more complex than single gene
30
What are chromosomal disorders?
have different number ie down syndrome 3 instead of 2
31
what is gene therapy
consists of modifying specific gene in order to treat or prevent a specific disease
32
What does genetic testing do?
1. identify disorder, 2. confirm dx, 3. identify carriers, r. identify those at risk of dev disease but do not have it currently
33
Human Genome Project
completed in 2003, map the sequencing of genes on chromosomes
34
What is a Human Genome?
map, pattern, of chromosomal and gene arrangements, the basis for genetics in humans
35
issues with genetic testing
1.testing has surpassed therapies, 2. privacy rights, rights of pts to participate in health related decisions 3. expensive 4. risks with testing (ins coverage loss)
36
Where else is genetic testing used?
1. paternity, 2. crimes
37
Behavioral genetics
understand beh thru heredity and biological influences. Seems some beh are hereditary and some are env.
38
Rate of Development
hereditary factor, how quickly a child develops "big/small for age"
39
Prenatal influences on the developmental process
prenatal env due to mom health, nutrition, pathogenic orgs, and substances in blood (alchohol, tobacco, drugs) FAS, folic acid and Spina Bifida, EMOTION/STRESS, abuse during preg. Neg impact. Positive experiences have pos impact
40
Environmental influences on developmental process
1. physical env. - play outside, experiences, clubs/orgs, sports, incidental learning building, digging, time with family,
41
Safety
primary concern on growth
42
social environment
trust/distrust b. worth, c. nurture/neglect, d. structure/chaos, e. comfort/suffering
43
Culture and Socioeconomic level
culture: belief, ideas, values,customs, child learn from adults arouond them
44
Home and development
responsive to needs, health practices, type of parenting style, anxious parents
45
Types of abuse
physical (beatings, sex) verbal (put down, guilt), emotional, actions (dark rooms) heavy burdn on child
46
School years
ready for school, differences in how kids respond to early school
47
Influence
as children they cannot choose heredity, home env, devl influences, but can mature and direct choices as adults
48
What is prejudice
negative feelings toward people from other race, or subcultures. Adults can change early learnings and choose beliefs
49
Value system
degree of importance attached to various beliefs, ideas or material things, incl honesty, truthfulness, achievement, love friendship, material possessions, religion, work, family
50
Standards of behavior
own personal rules and regulations
51
Adult responsibilities for behavior
1. recog neg behavior take control, positive beh, sound decisions, ineffecive beh get in wa of goals
52
Health care and behavior
understanding behav and people helps est rapport,
53
What happens when a pt is difficult
try to understand the reasons why, may be needs not being met, pleasant pts may be covering up
