Forensic Science Techniques Questions
How does molecular forensics contribute to the field of forensic science?
-
It provides strong evidence for criminal investigations
-
It helps in identifying missing persons and human remains
-
It aids in paternity testing and family lineage analysis
-
All of the above
D
Correct answer
Explanation
Molecular forensics plays a vital role in forensic science by providing strong evidence for criminal investigations, assisting in the identification of missing persons and human remains, and aiding in paternity testing and family lineage analysis.
What are the limitations of molecular forensics?
-
It can be expensive and time-consuming
-
It may not be able to provide conclusive evidence in all cases
-
It can be subject to contamination and errors
-
All of the above
D
Correct answer
Explanation
Molecular forensics, while powerful, has certain limitations, including its cost and time requirements, the possibility of inconclusive results in some cases, and the potential for contamination and errors during sample collection, handling, and analysis.
What is the primary mechanism of action of cryosurgery?
-
Thermal destruction
-
Mechanical destruction
-
Chemical destruction
-
Electrical destruction
A
Correct answer
Explanation
Cryosurgery works by freezing tissue, causing it to be destroyed.
Which of the following is NOT a type of physical evidence commonly collected at a crime scene?
-
Fingerprints
-
DNA
-
Bloodstains
-
Digital Data
D
Correct answer
Explanation
Digital data is not typically considered physical evidence in the traditional sense, as it is not a tangible object that can be physically collected and analyzed.
What is the primary role of a forensic scientist?
-
To conduct experiments and research in a laboratory
-
To collect evidence at crime scenes
-
To analyze evidence and interpret findings
-
To testify in court as an expert witness
C
Correct answer
Explanation
The primary role of a forensic scientist is to analyze evidence collected at crime scenes and interpret the findings to help investigators understand the circumstances of a crime.
Which type of evidence is commonly used to determine the time of death?
-
Fingerprints
-
DNA
-
Rigor Mortis
-
Livor Mortis
D
Correct answer
Explanation
Livor Mortis, or the settling of blood in the body after death, is commonly used to determine the time of death.
What is the process of identifying and comparing fingerprints called?
-
Dactylography
-
Odontology
-
Ballistics
-
Trace Evidence Analysis
A
Correct answer
Explanation
Dactylography is the process of identifying and comparing fingerprints for the purpose of identification.
Which of the following is NOT a common type of trace evidence?
-
Fibers
-
Hair
-
Tool Marks
-
Bloodstains
D
Correct answer
Explanation
Bloodstains are not typically considered trace evidence, as they are usually visible to the naked eye and can be easily collected.
Which type of evidence is commonly used to determine the cause of death?
-
Fingerprints
-
DNA
-
Autopsy Report
-
Ballistics Report
C
Correct answer
Explanation
An autopsy report, which is a detailed examination of a body after death, is commonly used to determine the cause of death.

-
Dactylography
-
Odontology
-
Ballistics
-
Trace Evidence Analysis
C
Correct answer
Explanation
Ballistics is the process of analyzing and comparing firearms and ammunition to determine if they were used in a crime.
Which of the following is NOT a common type of forensic analysis?
-
