Interpretation:
Three possible sources of contamination of a crime scene by the first responders have to be listed.
Concept Introduction:
Forensics: The study of evidence discovered at a crime scene and used in court law.
DNA finger printing: This technique used to distinguish between individuals of the same species using only samples of their DNA.
Example: A murder victim is found. The forensics team retrieved a blood sample from the crime scene. They prepared DNA fingerprints of the blood sample, the victim and a suspect as fallows.
