EXAM QUESTIONS
QUESTION 1
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.
RATIONALE: The correct answer is accurate because it precisely defines the purpose and scope of an autopsy, which
involves examining a deceased person's body to gather information about the cause of death and pre-death conditions.
This definition highlights the medical and investigative aspects of an autopsy, aligning with the typical context in which
the term is used.
QUESTION 2
Blood Splatter
CORRECT ANSWER
Trusted by thousands of students and professionals worldwide Page 1 of 74
, 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.
RATIONALE: This explanation is correct because it highlights the crucial role of blood splatter patterns in reconstructing
the events surrounding a crime, allowing forensic experts to infer vital information about the source of the blood and the
circumstances of the incident. By analyzing the size, direction, and speed of the blood splatters, investigators can draw
conclusions about the type of wound, the movement of the perpetrator or victim, and the potential weapon used,
providing valuable clues for solving the crime.
QUESTION 3
Caliber
CORRECT ANSWER
The diameter of the bore of a rifled firearm, usually expressed in hundredths of an inch or in millimeters.
RATIONALE: The term "caliber" refers to a firearm's internal diameter, which is the key factor in determining the size of
ammunition it can fire, and this measurement is often used to identify and categorize firearms. Expressing this
measurement in hundredths of an inch or millimeters provides a precise and standardized way to compare and
communicate the size of different firearms, making it a widely accepted definition of caliber.
QUESTION 4
Composite Drawing
CORRECT ANSWER
A sketch of a suspect produced from eyewitness descriptions of one or more persons.
RATIONALE: A composite drawing is created by combining multiple eyewitness descriptions of a suspect, which is why
it's defined as a sketch of a suspect produced from eyewitness descriptions of one or more persons. This process
involves combining the individual descriptions of physical characteristics, such as facial features, hair, and clothing, to
create a single, representative image of the suspect.
QUESTION 5
Criminology
CORRECT ANSWER
The study of criminal activity and how it is dealt with by the law.
RATIONALE: Criminology is the study of criminal activity and how it is dealt with by the law because it combines the
scientific study of crime patterns and trends with the examination of the criminal justice system's response to these
crimes. This interdisciplinary approach allows criminologists to analyze the causes and consequences of crime, as well as
the effectiveness of various policies and interventions aimed at preventing and addressing criminal behavior.
QUESTION 6
DNA
Trusted by thousands of students and professionals worldwide Page 2 of 74
, CORRECT ANSWER
Deoxyribonucleic acid. Double helix strand. Genetic code (fingerprint). 50% from mom and 50% from dad.
ACGT.
RATIONALE: The provided answer correctly breaks down the fundamental structure and concept of DNA, including its
double helix structure, the genetic code that serves as a unique fingerprint, and its inheritance pattern of 50% from each
parent, which are key components that define DNA. By incorporating the nucleotide bases A, C, G, and T, the answer
comprehensively covers the basic elements of DNA, making it a complete and accurate representation of the concept.
QUESTION 7
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.
RATIONALE: DNA Electrophoresis is correct because it accurately describes the process of separating DNA fragments
based on their size using an electric field, which is a fundamental concept in molecular biology. This technique is widely
used in creating genetic profiles, such as in DNA fingerprinting, due to its ability to precisely separate DNA fragments
according to their size.
QUESTION 8
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)
RATIONALE: DNA profiling is the correct answer because it specifically refers to the process of analyzing DNA patterns to
identify or exclude individuals as sources of biological evidence, which aligns with the common understanding of the
term. This definition captures the core concept of DNA profiling as a tool in forensic science for determining parentage,
identifying individuals from bodily fluid stains, and other biological evidence.
QUESTION 9
Fingerprint
CORRECT ANSWER
The unique patterns created by skin ridges found on the palm sides of fingers and thumbs.
RATIONALE: The term "fingerprint" specifically refers to the unique patterns created by skin ridges found on the palm
sides of fingers and thumbs, making it a precise and accurate description. This definition is rooted in the etymology of
the word "fingerprint" and the scientific understanding of human anatomy, which distinguishes it from other possible
meanings.
QUESTION 10
Trusted by thousands of students and professionals worldwide Page 3 of 74
, 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.
RATIONALE: The correct answer is accurate because it highlights the intersection of science and law enforcement,
specifically focusing on the use of various scientific disciplines to analyze physical evidence in a crime lab. This emphasis
on applying scientific principles to law enforcement practices is what defines the field of forensic science, making the
description a comprehensive and precise definition of the subject.
QUESTION 11
Absolute Certainty
CORRECT ANSWER
ultimate sureness with no implication of possible change.
RATIONALE: This concept of "ultimate sureness" conveys a state of complete confidence in the truth of a statement,
implying that it is beyond doubt or uncertainty. The addition of "no implication of possible change" eliminates any
consideration of potential future developments or new information that could challenge or modify the certainty, thereby
solidifying it as absolute.
QUESTION 12
Accountability
CORRECT ANSWER
the quality of subordinate workers being responsible for his/her own work and answerable to a superior.
RATIONALE: This answer is correct because accountability implies a direct link between an individual's actions and their
responsibility for those actions, which is fulfilled when a subordinate worker is responsible for their own work and
answerable to a superior. This relationship establishes clear lines of authority and responsibility, enabling effective
oversight and consequences for any shortcomings.
QUESTION 13
Accuracy
CORRECT ANSWER
the degree of conformity of a measured quantity to its actual (true) value.
RATIONALE: Accuracy refers to the extent to which a measured quantity deviates from its true value, indicating
consistency between the measured and actual values. This definition highlights the concept that accuracy is about
getting close to the true value, rather than achieving precision or being consistently repeatable.
