All Forensics Exam Practice Questions Fully
Solved & Graded A+
Autopsy - Answer The internal and external examination of a body after death. An autopsy is performed
to confirm or determine the cause of death and establish other pre-death conditions, such as the type of
food last consumed and the time it was consumed.
Ballistics - Answer The study of the motion of bullets and their examination for distinctive characteristics
after being fired. Examiners can use this evidence to match bullets or bullet fragments to specific
weapons.
Blood Splatter - Answer The pattern of blood that has struck a surface. This pattern can provide vital
information about the source of the blood. Can help determine the size and type of wound, the
direction and the speed with which the perpetrator or victim was moving, and the type of weapon used
to create the blood spill.
Caliber - Answer The diameter of the bore of a rifled firearm, usually expressed in hundredths of an inch
or in millimeters.
Composite Drawing - Answer A sketch of a suspect produced from eyewitness descriptions of one or
more persons.
Criminology - Answer The study of criminal activity and how it is dealt with by the law.
DNA - Answer Deoxyribonucleic acid. Double helix strand. Genetic code (fingerprint). 50% from mom
and 50% from dad. ACGT.
DNA Electrophoresis - Answer The technique by which DNA fragments are placed in a gel and charged
with electricity. An applied electric field then separates the fragments by size, as part of the process of
creating a genetic profile.
DNA Profiling - Answer The process of testing to identify DNA patterns or types. In forensic science this
testing is used to indicate parentage or to exclude or include individuals as possible sources of bodily
fluid stains (blood, saliva, semen) and other biological evidence (bones, hair, teeth)
,Evidence - Answer Anything that has been used, left, removed, altered, or contaminated during the
commission of a crime or other event under investigation
Fingerprint - Answer The unique patterns created by skin ridges found on the palm sides of fingers and
thumbs.
Forensic Science - Answer The application of science to law. The application of science to those criminal
and civil laws that are enforced by police agencies in a criminal justice system. The focus of forensics is
the crime lab. The crime lab uses the principles and technique of biology, chemistry, physics, geology,
anthropology, and other sciences in order to place physical evidence into a professional discipline.
Absolute Certainty - Answer ultimate sureness with no implication of possible change.
Accountability - Answer the quality of subordinate workers being responsible for his/her own work and
answerable to a superior.
Accuracy - Answer the degree of conformity of a measured quantity to its actual (true) value.
Acetone - Answer a colorless, highly flammable chemical compound used as an organic solvent, an
ingredient in many lacquer thinner compounds and adhering liquids.
Accelerant - Answer an agent, often an ignitable liquid, that acts to initiate a fire or increase its rate of
spread.
Administrative documentation - Answer records such as case related conversations, evidence receipts,
description of evidence packaging and seals, and other pertinent information.
Administrative (or Laboratory Director) Case File Review - Answer a detailed final review of the case file
documentation. A member other than the assigned analyst must conduct the Laboratory Director case
file review on all case files.
Algor mortis - Answer the postmortem cooling of the body.
, Analytical Data - Answer all case specific records such as notes, worksheets, graphs, spectra, printouts,
computer data files, photographs, photocopies, microscopic slides and other data or records.
Analytical Procedure - Answer an orderly step-by-step process designed to ensure operational
uniformity and to minimize systematic variability.
Analyst - Answer any ADFS personnel assigned to perform scientific investigation or evidential
examination.
Ante mortem - preceding death Antigens - Answer foreign substances in the body that are capable of
causing disease.
Arson - Answer the intentional and unlawful burning of a building or other property.
Assessment - Answer the process of evaluating analysts to determine their level of technical knowledge,
skills, and abilities.
Asphyxiation - Answer a medical term for suffocation, which leads to lack of oxygen in the blood.
Audit - Answer a review conducted to compare the various aspects of the laboratory's performance with
a standard for that performance.
Back spatter - Answer blood directed back toward the source of energy or force that caused the spatter;
often associated with entrance gunshot wounds.
Ballistics - Answer branch of physics that deals with the flights of projectiles.
Base pair - Answer combination of 2 nucleotides (A and T or G and C) held together by weak hydrogen
bonds; the DNA double helix is formed when a base pair of nucleotides in the DNA strands are
connected by these bonds.
