Questions And Answers
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.
@GoldenMinds
,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.
@GoldenMinds
, 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 -
Blind or Double-Blind Sample Technique. ANSWER - a type of proficiency testing
where the member is not aware that the sample/case under analysis is a quality
assessment sample.
Blood borne pathogens. ANSWER - pathogenic microorganisms in blood or other
body fluids that can cause disease in people. These pathogens include, but are not
limited to, hepatitis B virus (HBV) and human immunodeficiency virus (HIV) in all of
its forms.
