PBS Final Exam Review questions with
complete answers
biomedical science - 🔷ANSWERS 🖊✔✔the application of the principles of the natural sciences,
especially biology and physiology, to clinical medicine
control group - 🔷ANSWERS 🖊✔✔the group in an experiment where the independent variable being
tested is not applied so that it may serve as a standard for comparison against the experimental group
where the independent variable is applied
dependent variable - 🔷ANSWERS 🖊✔✔the measurable effect, outcome, or response in which the
research is interested
experiment - 🔷ANSWERS 🖊✔✔a research study conducted to determine the effect that one variable
has upon another variable
forensic science - 🔷ANSWERS 🖊✔✔the application of scientific knowledge to questions of civil and
criminal law
hypothesis - 🔷ANSWERS 🖊✔✔clear prediction of the anticipated results of an experiment
independent variable - 🔷ANSWERS 🖊✔✔the variable that is varied or manipulated by the researcher
negative control - 🔷ANSWERS 🖊✔✔control group where conditions produce a negative outcome, this
helps identify outside influences which may present that were not accounted for when the procedure
was created
personal protective equipment - 🔷ANSWERS 🖊✔✔specialized clothing or equipment, worn by an
employee for protection against infectious materials (as defined by OSHA)
, positive control - 🔷ANSWERS 🖊✔✔group expected to have a positive result, allowing the researcher
to show that the experimental set up was capable of producing results
a - 🔷ANSWERS 🖊✔✔a purine base, that by chargaff's rules is paired with t
chromosome - 🔷ANSWERS 🖊✔✔any of the usually linear bodies in the cell nucleus that contain the
genetic material
c - 🔷ANSWERS 🖊✔✔a pyrimidine base, the by chargaff's rules pairs with g
DNA - 🔷ANSWERS 🖊✔✔a double stranded, helical nucleic acid molecule capable of replicating and
determining the inherited structure of a cell's proteins
gel electrophoresis - 🔷ANSWERS 🖊✔✔the separation of nucleic acids or proteins, on the basis of their
size and electrical charge, by measuring their rate of movement through an electrical field in a gel
gene - 🔷ANSWERS 🖊✔✔a discrete unit of hereditary information consisting of a specific nucleotide
sequence in DNA (or RNA, in some viruses)
g - 🔷ANSWERS 🖊✔✔a purine base, that by chargaff's rules pairs with c
helix - 🔷ANSWERS 🖊✔✔something spiral in form
model - 🔷ANSWERS 🖊✔✔a simplified version of something complex used, for example, to analyze
and solve problems or make predictions
nucleotide - 🔷ANSWERS 🖊✔✔a building block of DNA, consisting of a five carbon sugar covalently
bonded to a nitrogenous base and a phosphate group
restriction enzyme - 🔷ANSWERS 🖊✔✔a degradative enzyme that recognizes specific nucleotide
sequences and cuts up DNA
