PRINCIPLES OF BIOMEDICAL SCIENCE
CERTIFICATION EVALUATION TESTED
QUESTIONS AND ANSWERS COMPLETE
REVIEW
●● Control Group
Answer: 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
Answer: The measurable effect, outcome, or response in which the
research is interested.
●● Experiment
Answer: A research study conducted to determine the effect that one
variable has upon another variable.
●● Forensic Science
Answer: The application of scientific knowledge to questions of civil
and criminal law.
,●● Hypothesis
Answer: Clear prediction of the anticipated results of an experiment.
●● Independent Variable
Answer: The variable that is varied or manipulated by the researcher.
●● Negative Control
Answer: Control group where conditions produce a negative outcome.
Negative control groups help identify outside influences which may be
present that were not accounted for when the procedure was created.
●● Positive Control
Answer: Group expected to have a positive result, allowing the
researcher to show that the experimental set up was capable of
producing results.
●● Personal Protective Equipment
Answer: Specialized clothing or equipment, worn by an employee for
protection against infectious materials (as defined by OSHA).
●● Adenine
Answer: A component of nucleic acids, energy-carrying molecules such
as ATP, and certain coenzymes. Chemically, it is a purine base. Pairs
with thymine in DNA
,●● Chromosome
Answer: Any of the usually linear bodies in the cell nucleus that contain
the genetic material.
●● Cytosine
Answer: A component of nucleic acids that carries hereditary
information in DNA and RNA in cells. Chemically, it is a pyrimidine
base. Pairs with guanine in DNA
●● DNA
Answer: A double-stranded, helical nucleic acid molecule capable of
replicating and determining the inherited structure of a cell's proteins.
●● Gel Electrophoresis
Answer: 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
Answer: A discrete unit of hereditary information consisting of a specific
nucleotide sequence in DNA (or RNA, in some viruses).
●● Guanine
, Answer: A component of nucleic acids that carries hereditary
information in DNA and RNA in cells. Chemically, it is a purine base.
Pairs with cytosine in DNA
●● Helix
Answer: Something spiral in form.
●● Model
Answer: A simplified version of something complex used, for example,
to analyze and solve problems or make predictions.
●● Nucleotide
Answer: A building block of DNA, consisting of a five-carbon sugar
covalently bonded to a nitrogenous base and a phosphate group.
●● Restriction Enzyme
Answer: A degradative enzyme that recognizes specific nucleotide
sequences and cuts up DNA.
●● Restriction Fragment Length Polymorphisms (RFLPs)
Answer: Differences in DNA sequence on homologous chromosomes
that can result in different patterns of restriction fragment lengths (DNA
segments resulting from treatment with restriction enzymes).
