Exam Questions and Answers 100%
Pass
Biomedical Science - ✔✔The application of the principles of the natural sciences,
especially biology and physiology, to clinical medicine.
Control Group - ✔✔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 - ✔✔The measurable effect, outcome, or response in which the
research is interested.
Experiment - ✔✔A research study conducted to determine the effect that one variable
has upon another variable.
Forensic Science - ✔✔The application of scientific knowledge to questions of civil and
criminal law.
Hypothesis - ✔✔Clear prediction of the anticipated results of an experiment.

,Independent Variable - ✔✔The variable that is varied or manipulated by the researcher.
Negative Control - ✔✔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 - ✔✔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 - ✔✔Specialized clothing or equipment, worn by an
employee for protection against infectious materials (as defined by OSHA).
Adenine - ✔✔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 - ✔✔Any of the usually linear bodies in the cell nucleus that contain the
genetic material.
Cytosine - ✔✔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 - ✔✔A double-stranded, helical nucleic acid molecule capable of replicating and
determining the inherited structure of a cell's proteins.

, Gel Electrophoresis - ✔✔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 - ✔✔A discrete unit of hereditary information consisting of a specific nucleotide
sequence in DNA (or RNA, in some viruses).
Guanine - ✔✔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 - ✔✔Something spiral in form.
Model - ✔✔A simplified version of something complex used, for example, to analyze
and solve problems or make predictions.
Nucleotide - ✔✔A building block of DNA, consisting of a five-carbon sugar covalently
bonded to a nitrogenous base and a phosphate group.
Restriction Enzyme - ✔✔A degradative enzyme that recognizes specific nucleotide
sequences and cuts up DNA.
Restriction Fragment Length Polymorphisms (RFLPs) - ✔✔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).
