PLTW - MEDICAL INTERVENTIONS
FINAL EXAM STUDY GUIDE
QUESTIONS WITH ANSWERS.
What is sound? - correct answer -A disturbance that travels
through a medium as a longitudinal wave
Case-Control Study - correct answer -A type of epidemiological
study where a group of individuals with the disease, referred to as
cases, are compared to individuals without the disease, referred
to as controls.
Cohort Study - correct answer -A type of epidemiological study
where a groups of exposed individuals (who have been exposed
to the potential risk factor) and a group of non-exposed individuals
are followed over time to determine the incidence of disease
DNA ligase - correct answer -A linking enzyme essentials for DNA
replication and recombinant DNA techniques.

Epidemic - correct answer -Affecting an atypically large number of
individuals within a population, community, or region at the same
time.
Epidemiology - correct answer -A branch of medical science that
deals with the incidence, distribution, and control of disease in a
population.
Inoculation - correct answer -The introduction of a pathogen or
antigen into a living organism to stimulate the production of
antibodies.
Plasmid - correct answer -A small ring of DNA that carries
accessory genes separate from those of the bacterial
chromosome.
Recombinant DNA - correct answer -A DNA molecule made in
vitro with segments from different sources.
Restriction Enzyme - correct answer -A degradative enzyme that
recognizes specific nucleotide sequences and cuts up DNA.

Vaccine - correct answer -A harmless variant of a pathogen that
stimulates a host's immune system to mount defenses against the
pathogen.
Amniocentesis - correct answer -A technique for determining
genetic abnormalities in a fetus by the presence of certain
chemicals or defective fetal cells in the amniotic fluid, obtained by
aspiration from a needle inserted into the uterus.
Anneal - correct answer -To be capable of combining with
complementary nucleic acid by a process of heating and cooling
Carrier Screening - correct answer -Indiscriminate examination of
members of a population to detect heterozygotes for serious
disorders
Chorionic Villus Sampling - correct answer -A technique for
diagnosing genetic and congenital defects in a fetus by removing
and analyzing a sample of the fetal portion of the placenta.
