Forensic Science Techniques Questions
Which technology is used for genetic analysis and conservation genomics?
-
DNA sequencing
-
Genetic markers
-
Population genomics
-
All of the above
D
Correct answer
Explanation
Technology, including DNA sequencing, genetic markers, and population genomics, enables genetic analysis and conservation genomics, providing insights into genetic diversity, population structure, and evolutionary relationships among wildlife species.
Which technique is used to amplify a specific DNA sequence?
-
DNA Sequencing
-
DNA Fingerprinting
-
Polymerase Chain Reaction
-
Southern Blotting
C
Correct answer
Explanation
Polymerase Chain Reaction (PCR) is a technique used to amplify a specific DNA sequence by repeatedly copying it using a thermostable DNA polymerase.
Which technique is used to separate DNA fragments based on their size?
-
DNA Sequencing
-
DNA Fingerprinting
-
Gel Electrophoresis
-
Southern Blotting
C
Correct answer
Explanation
Gel Electrophoresis is a technique used to separate DNA fragments based on their size by applying an electric current to a gel containing the DNA samples.
Which of the following is NOT a type of physical evidence commonly collected at a crime scene?
-
Fingerprints
-
DNA
-
Bullet casings
-
Shoe prints
D
Correct answer
Explanation
Shoe prints are not typically considered physical evidence, as they are not unique to an individual and can be easily transferred from one person to another.
What is the primary role of a forensic pathologist?
-
To determine the cause and manner of death
-
To collect and analyze DNA evidence
-
To examine fingerprints and other trace evidence
-
To reconstruct crime scenes
A
Correct answer
Explanation
Forensic pathologists are responsible for determining the cause and manner of death in cases where the cause of death is not immediately apparent or is suspicious.
Which of the following is a type of forensic analysis that involves the examination of hair and fibers?
-
DNA analysis
-
Fingerprint analysis
-
Ballistics analysis
-
Trace evidence analysis
D
Correct answer
Explanation
Trace evidence analysis involves the examination of small pieces of evidence, such as hair and fibers, that can be transferred from one person or object to another.
What is the term for the process of matching a fingerprint to a known individual?
-
Fingerprint identification
-
Fingerprint comparison
-
Fingerprint analysis
-
Fingerprint classification
A
Correct answer
Explanation
Fingerprint identification is the process of matching a fingerprint to a known individual by comparing the unique patterns of ridges and valleys on the fingerprint.
Which of the following is NOT a type of forensic analysis that can be used to identify a suspect?
-
DNA analysis
-
Fingerprint analysis
-
Ballistics analysis
-
Bloodstain pattern analysis
D
Correct answer
Explanation
Bloodstain pattern analysis is not typically used to identify a suspect, as it is more commonly used to reconstruct crime scenes and determine the sequence of events that led to a crime.
Which of the following is NOT a type of evidence that can be collected at a crime scene?
-
Fingerprints
-
DNA
-
Bullet casings
-
Eyewitness testimony
D
Correct answer
Explanation
Eyewitness testimony is not considered physical evidence, as it is not a tangible object that can be collected and analyzed.
What is the term for the process of reconstructing a crime scene based on the evidence that is collected?
-
Crime scene reconstruction
-
Forensic analysis
-
Evidence collection
-
Crime scene investigation
A
Correct answer
Explanation
Crime scene reconstruction is the process of reconstructing a crime scene based on the evidence that is collected, in order to determine the sequence of events that led to the crime.
Which of the following is NOT a type of forensic analysis that can be used to analyze digital evidence?
-

Which of the following is NOT a type of forensic analysis that can be used to analyze trace evidence?
-
Microscopy
-
Spectroscopy
-
Chromatography
-

-
Bloodstain pattern analysis
-
Forensic analysis
-
Crime scene reconstruction
-
Evidence collection
A
Correct answer
Explanation
Bloodstain pattern analysis is the process of analyzing the patterns of bloodstains at a crime scene to determine the sequence of events that led to the crime.
