ALL FORENSICS TSA EXAM QUESTIONS
COMPLETE WITH 100% CORRECT
ANSWERS
\.Autopsy - ANSWERS-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 - ANSWERS-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 - ANSWERS-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 - ANSWERS-The diameter of the bore of a rifled firearm, usually
expressed in hundredths of an inch or in millimeters.
\.Composite Drawing - ANSWERS-A sketch of a suspect produced from eyewitness
descriptions of one or more persons.
,\.Criminology - ANSWERS-The study of criminal activity and how it is dealt with by
the law.
\.DNA - ANSWERS-Deoxyribonucleic acid. Double helix strand. Genetic code
(fingerprint). 50% from mom and 50% from dad. ACGT.
\.DNA Electrophoresis - ANSWERS-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 - ANSWERS-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 - ANSWERS-Anything that has been used, left, removed, altered, or
contaminated during the commission of a crime or other event under
investigation
\.Fingerprint - ANSWERS-The unique patterns created by skin ridges found on the
palm sides of fingers and thumbs.
\.Forensic Science - ANSWERS-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 - ANSWERS-ultimate sureness with no implication of possible
change.
\.Accountability - ANSWERS-the quality of subordinate workers being responsible
for his/her own work and answerable to a superior.
\.Accuracy - ANSWERS-the degree of conformity of a measured quantity to its
actual (true) value.
\.Acetone - ANSWERS-a colorless, highly flammable chemical compound used as
an organic solvent, an ingredient in many lacquer thinner compounds and
adhering liquids.
\.Accelerant - ANSWERS-an agent, often an ignitable liquid, that acts to initiate a
fire or increase its rate of spread.
\.Administrative documentation - ANSWERS-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 - ANSWERS-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.
