PBS PLTW EOC REVIEW EXAM STUDY GUIDE. Biomedical science - answerthe application of the principles of the natural sciences, especially biology and physiology control group - answerthe 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 - answerthe measurable effect, outcome, or response in which the research is inerested experiment - answera research study conducted to determine the effect that one variable has upon another variable forensic science - answerthe application of scientific knowledge to questions of civil and criminal law hypothesis - answerclear prediction of the anticipated results of an experiment independent variable - answerthe variable that is varied or manipulated by the researcher negative control - answercontrol 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 - answerspecialized clothing or equipment worn by an employee for protection against infectious materials positive control - answergroup expected to have a positive result, allowing the researcher t show that the experimental set up was capable of producing results adenine - answera component of nucleic acids, energy-carrying molecules such as ATP, and certain co-enzymes. Chemically, it is a purine base chromosome - answerany of the usually linear bodies in the cell nucleus that contain the genetic material cytosine - answera component of nucleic acids that carries hereditary information in DNA and RNA in cells. chemically it is a pyrimidine base Deoxyribonucleic acid (DNA) - answera double-stranded helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell;s proteins gel elctrophoresis - answerthe separation of nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins gene - answera discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA in some viruses) guanine - answera component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically, it is a purine base helix - answersomething in spiral form model - answersimplified version of something complex used, for example, to analyze and solve problems or make predicitons nucleotide - answera building block of DNA, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group restriction enzyme - answera degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA Restriction fragment length polymorphisms (RFLPs) - answerdifferences 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 - answera component of nucleic acid that carries hereditary information in DNA in cells. Chemically, it is a pyrimidine base autopsy - answeran examination of the body after death usually with such dissection as will expose the cital organs for determining the cause of death bibliography - answera document showing all the sources used to research information medical examiner - answera physician who performs an autopsy when death may be accidental or violent. He or she may also serve in some jurisdictions ac the coroner during electrophoresis, what causes DNA to move out of the wells and through the gel? - answerthe electric current moves DNA (negative charge) towards the positive side of the gel what are two ways for a forensic pathologist to tell the time of death - answeralgor mortis and livitity what are the 5 manners of death - answerhomicide, suicide, accident, natural, undefined write a strand of DNA that would bind with this strand:
