DNA comparison in forensic investigations involves analyzing DNA samples collected from crime scenes and comparing them to DNA samples from potential suspects. This process helps in identifying individuals involved in a crime and linking them to the evidence found at the scene. For example, if DNA from a suspect matches DNA found at the crime scene, it can provide strong evidence linking the suspect to the crime. This scientific method has been instrumental in solving crimes such as murders, sexual assaults, and burglaries by providing crucial evidence to law enforcement agencies.
