⩥ Function of activator and repressor sites. Answer: monitor protein
product levels and regulate GE
- product level down = increase transcription
- product level up = decrease transcription
⩥ Chromosomes. Answer: 1 from mom, 1 from dad
46 single or 23 pairs
22 are autosomes, 1 sex
male XY, female XX
***only 1 X in females control expression of traits but both XX
activated in gametogenesis
⩥ Mitosis. Answer: - replication of non-germ cell
- repair tissue, wound healing
- increase tissue mass
- duplicate chromosomes and divide in 2
,⩥ Meisois Answer: - germ cell production
- only once in cell line
- results in ovum and sperm
- 4 daughter cells produced
⩥ Allele Answer: alternate form of a gene
⩥ Locus Answer: location on chromosome
⩥ Penetrance Answer: The percentage of individuals with a particular
genotype that actually displays the phenotype associated with the
genotype
⩥ Expressitivity Answer: manner in which a gene is expressed in the
phenotype; may be mild to severe
⩥ How are most human traits determined? Answer: by multiple pairs of
genes
⩥ Monogenic/Mendelian inheritance Answer: only 1 pair of genes
involved in transmission of info
⩥ Polygenic inheritance Answer: multiple genes at different loci have
additive effect in determining trait
,⩥ Multifactorial inheritance Answer: multiple genes and environmental
factors contribute
its less predictable
⩥ Which of the following statements is true regarding drug therapy and
its effects on the body?
a) Drugs only have positive effects on cells.
b) Drugs do not injure tissues or cells.
c) Antineoplastic cells directly damage cells.
d) Drugs only have bad effects when they have side effects. Answer: c)
Antineoplastic cells directly damage cells.
Explanation:
Antineoplastic drugs directly injure cells. Many drugs injure tissues and
cells either through their direct mechanism of action, side effects, or
adverse effects.
⩥ Which of the following clients are at high risk for developing dilated
cardiomyopathy?
a) 17 year old with a diving injury resulting in paraplegia.
b) 78 year old Alzheimer's patient who received a third degree burn
following an oven fire.
c) 44 year old noncompliant female who forgets to take her
hypertensive medications.
, d) 4 year old child born with cerebral palsy and confined to a
wheelchair. Answer: c) 44 year old noncompliant female who forgets to
take her hypertensive medications.
Explanation:
In hypertension, the increased workload required to pump blood against
an elevated arterial pressure in the aorta results in a progressive increase
in LV muscle mass and need for coronary blood flow. The pressure
overload causes hypertrophied cells to have greater width and length.
Paraplegia, cerebral palsy and Alzheimer's disease does not increase the
workload of the cardiac muscle per se.
⩥ A nurse is assessing a patient who is a body builder. The nurse
documents the increased size of the patient's muscle as resulting from
which of the following?
a) Atrophy
b) Hypertrophy
c) Dysplasia
d) Hyperplasia Answer: b) Hypertrophy
Explanation:
Hypertrophy represents an increase in cell size and with it an increase in
the amount of functioning tissue mass (Fig. 5.2). It results from an
increased workload imposed on an organ or body part and is commonly
seen in cardiac and skeletal muscle. tissue, which cannot adapt to an
increase in workload through mitotic division and formation of more
cells.1
