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.

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
