Frequently Asked Questions
What are the main branches of forensic science typically covered in a final exam?
The main branches include forensic toxicology, fingerprint analysis, DNA analysis, ballistics, forensic anthropology, and crime scene investigation.
How important is the chain of custody in forensic investigations?
The chain of custody is crucial because it ensures the integrity and authenticity of evidence, preventing contamination or tampering, and is essential for evidence to be admissible in court.
What techniques are commonly used in fingerprint analysis for forensic identification?
Common techniques include powder dusting, superglue fuming, digital imaging, and automated fingerprint identification systems (AFIS).
How does forensic DNA analysis contribute to solving crimes?
Forensic DNA analysis allows for the identification of suspects and victims with high accuracy by comparing DNA samples collected from crime scenes to known profiles in DNA databases.
What role does forensic toxicology play in criminal investigations?
Forensic toxicology involves analyzing biological samples to detect drugs, poisons, or other toxins, helping determine cause of death or influence on behavior at the time of the crime.
What are the key ethical considerations in forensic science exams and practice?
Key considerations include maintaining objectivity, avoiding contamination, ensuring evidence integrity, respecting privacy rights, and presenting unbiased, accurate results.
