PLTW Biomedical Final Exam Questions and Answers 100% Pass Biomedical Science - Application of the principles of natural sciences, especially biology and physiology, to clinical medicine. Experiment - A research study conducted to determine the effect that one variable has upon another variable. Independent Variable - The variable that is varied or manipulated by the researcher. Positive Control - Group expected to have a positive result, allowing the researcher to show that the experimental set up was capable of producing results. 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. Forensic Science - The application of scientific knowledge to questions of civil and criminal law. 2Brittie Donald, All Rights Reserved © 2025 Negative Control - Control group where conditions produce a negative outcome.

Chromosome - Any of the usually linear bodies in the cell nucleus that contain the genetic material. Deoxyribonucleic Acid - 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).

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 Polymorphism - 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). Autopsy - An examination of the body after death usually with such dissection as will expose the vital organs for determining the cause of death. Confidentiality - A set of rules or a promise that li
