ALL FORENSICS TSA EXAM QUESTIONS AND ANSWERS
Autopsy - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER✅✅✅The diameter of the bore of a rifled firearm, usually expressed in
hundredths of an inch or in millimeters.
Composite Drawing - CORRECT ANSWER✅✅✅A sketch of a suspect produced from eyewitness
descriptions of one or more persons.
Criminology - CORRECT ANSWER✅✅✅The study of criminal activity and how it is dealt with by the
law.
DNA - CORRECT ANSWER✅✅✅Deoxyribonucleic acid. Double helix strand. Genetic code
(fingerprint). 50% from mom and 50% from dad. ACGT.
DNA Electrophoresis - CORRECT 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 - CORRECT 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 - CORRECT ANSWER✅✅✅Anything that has been used, left, removed, altered, or
contaminated during the commission of a crime or other event under investigation
Fingerprint - CORRECT ANSWER✅✅✅The unique patterns created by skin ridges found on the palm
sides of fingers and thumbs.
Forensic Science - CORRECT 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 - CORRECT ANSWER✅✅✅ultimate sureness with no implication of possible
change.
Accountability - CORRECT ANSWER✅✅✅the quality of subordinate workers being responsible for
his/her own work and answerable to a superior.
Accuracy - CORRECT ANSWER✅✅✅the degree of conformity of a measured quantity to its actual
(true) value.
Acetone - CORRECT ANSWER✅✅✅a colorless, highly flammable chemical compound used as an
organic solvent, an ingredient in many lacquer thinner compounds and adhering liquids.
Accelerant - CORRECT ANSWER✅✅✅an agent, often an ignitable liquid, that acts to initiate a fire or
increase its rate of spread.
Administrative documentation - CORRECT 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 - CORRECT 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 - CORRECT ANSWER✅✅✅the postmortem cooling of the body.
Analytical Data - CORRECT 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 - CORRECT ANSWER✅✅✅an orderly step-by-step process designed to ensure
operational uniformity and to minimize systematic variability.
Analyst - CORRECT ANSWER✅✅✅any ADFS personnel assigned to perform scientific investigation or
evidential examination.
Ante mortem - preceding death Antigens - CORRECT ANSWER✅✅✅foreign substances in the body
that are capable of causing disease.
Arson - CORRECT ANSWER✅✅✅the intentional and unlawful burning of a building or other
property.
Assessment - CORRECT ANSWER✅✅✅the process of evaluating analysts to determine their level of
technical knowledge, skills, and abilities.
Asphyxiation - CORRECT ANSWER✅✅✅a medical term for suffocation, which leads to lack of oxygen
in the blood.
Audit - CORRECT ANSWER✅✅✅a review conducted to compare the various aspects of the
laboratory's performance with a standard for that performance.
