Question 1

What is forensic science?

Accepted Answer

The application of scientific methods to solve legal cases

Answer

Forensic science is the application of a broad spectrum of scientific principles and techniques to legal matters, particularly in the context of criminal and civil investigations. It involves collecting, preserving, and analyzing scientific evidence from crime scenes or other relevant locations. The goal is to provide objective, scientific findings that can assist law enforcement and the justice system in establishing facts and solving cases.

Question 2

Which of the following is a primary role of a forensic pathologist?

Accepted Answer

Determining the cause and manner of death

Answer

Forensic pathologists are medical doctors specializing in pathology who perform autopsies to investigate deaths that are sudden, unexpected, violent, or suspicious. Their primary role is to determine the medical cause of death (e.g., gunshot wound) and the manner of death (e.g., homicide, accident, natural). This crucial work provides vital information for legal proceedings and public health.

Question 3

What type of evidence is DNA considered?

Accepted Answer

Biological evidence

Answer

DNA is considered biological evidence because it originates from living organisms, such as humans, animals, or plants. It is found in bodily fluids, hair, skin cells, and other organic materials. This classification distinguishes it from physical evidence like fingerprints or tool marks, highlighting its unique nature as genetic material used for identification.

Question 4

What is the primary purpose of fingerprint analysis?

Accepted Answer

Linking a suspect to a crime scene through unique ridge patterns

Answer

Fingerprint analysis relies on the principle that every individual possesses unique and permanent friction ridge patterns on their fingertips. The primary purpose is to compare latent prints found at a crime scene with known prints from suspects or databases. This comparison allows investigators to establish a direct link between an individual and the crime, serving as powerful identification evidence.

Question 5

Which tool is commonly used in forensic toxicology?

Accepted Answer

Gas chromatograph

Answer

A gas chromatograph (GC) is a common analytical instrument used in forensic toxicology to separate and identify volatile compounds in a sample. It is particularly effective for detecting and quantifying drugs, alcohol, and poisons in biological specimens like blood or urine. This allows forensic toxicologists to determine the presence and concentration of substances that may have contributed to a death or impairment.
