All Forensics TSA Questions and Answers
with Complete Solutions Top Graded 2024
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.
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)
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.
Bile - Answer--a digestive fluid made by the liver and stored in the gallbladder that helps
digest fats.
Biology - the science that studies living organisms. - Answer--
