biomedical science correct answer: the application of the principles of the natural sciences, especially biology and physiology control group correct 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 correct answer: the measurable effect, outcome, or response in which the research is inerested experiment correct answer: a research study conducted to determine the effect that one variable has upon another variable forensic science correct answer: the application of scientific knowledge to questions of civil and criminal law hypothesis correct answer: clear prediction of the anticipated results of an experiment independent variable correct answer: the variable that is varied or manipulated by the researcher negative control correct 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 personal protective equipment correct answer: specialized clothing or equipment worn by an employee for protection against infectious materials positive control correct answer: group expected to have a positive result, allowing the researcher t show that the experimental set up was capable of producing results adenine correct answer: a component of nucleic acids, energy-carrying molecules such as ATP, and certain co-enzymes. Chemically, it is a purine base chromosome correct answer: any of the usually linear bodies in the cell nucleus that contain the genetic material cytosine correct answer: a component of nucleic acids that carries hereditary information in DNA and RNA in cells. chemically it is a pyrimidine base Deoxyribonucleic acid (DNA) correct answer: a double-stranded helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell;s proteins gel elctrophoresis correct answer: the separation of nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins gene correct answer: a discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA in some viruses) guanine correct answer: a component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically, it is a purine base helix correct answer: something in spiral form model correct answer: simplified version of something complex used, for example, to analyze and solve problems or make predicitons nucleotide correct answer: a building block of DNA, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group restriction enzyme correct answer: a degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA Restriction fragment length polymorphisms (RFLPs) correct 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) thymine correct answer: a component of nucleic acid that carries hereditary information in DNA in cells. Chemically, it is a pyrimidine base autopsy correct answer: an examination of the body after death usually with such dissection as will expose the cital organs for determining the cause of death bibliography correct answer: a document showing all the sources used to research information medical examiner correct answer: a 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? correct answer: the 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 correct answer: algor mortis and livitity what are the 5 manners of death correct answer: homicide, suicide, accident, natural, undefined write a strand of DNA that would bind with this strand: A T C G T C A G G correct answer: T A G C A G T C C what are the three primary fingerprint ridge patterns? correct answer: plain, whorl, and radial What is the Glastier equaison (to find time of death) correct answer: 98.4 - recorded temp / 1.5 hours = # of hours since death glucagon correct answer: a protein hormone secreted by pancreatic endocrine cells that raises blood glucose levels; an antagonistic hormone to insulin
