DNA analysis is crucial to forensic investigation as it allows investigators to determine to whom, a specific evidence found at a crime scene such as blood, saliva, body fluids, skin cells, hair, etc, might belong– which helps in the identification of suspects and victims. DNA analysis can produce evidence of a suspect’s presence at a crime scene during the time at which the crime was committed, which acts as conclusive evidence. It is also used in cases requiring a determination of parentage (paternity test) and cases where proof of rape or sexual assault is required. DNA analysis is also crucial in cases of mass disasters to identify the bodies of victims. Thus, DNA evidence is a key part of forensic investigations as it is conclusive proof of identity.
