What is biomedical science?
The applications of 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.
Personal Protective Equipment
Specialized clothing or equipment, worn by an employee for protection against infectious materials (as defined by OSHA).
Positive Control
Group expected to have a positive result, allowing the researcher to show that the experimental set up was capable of producing results.
Adenine
A component of nucleic acids, energy-carrying molecules such as ATP, and certain coenzymes. Chemically, it is a purine base.
Chromosome
Carrying genetic infomation in the form of genes
Cytosine
A component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically, it is a pyrimidine base.
Deoxyribonucleic Acid (DNA)
A double-stranded, molecule capable of replicating
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 hereditary unit that is transformed from parent to offspring and helps determine characteristic of offspring
Guanine
A component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically, it is a purine base.
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).
Thymine
A component of nucleic acid that carries hereditary information in DNA in cells. Chemically, it is a pyrimidine base.
Autopsy
The examination of a dead corpse to determine cause of death
