Definition - What does DNA Profiling mean?
DNA profiling is the process of using DNA to identify suspects. The reason why DNA profiling is often used for this purpose is because DNA is genetic information that is unique for every single person. So, if a person's DNA is found at a crime scene, then this is a strong indicator that the person was involved in the crime.
Justipedia explains DNA Profiling
Possessing DNA evidence that was collected through DNA profiling can add a substantial amount of strength to a particular party's argument in a court of law.
DNA evidence can be particularly helpful for rape cases. The reason for this is because victims often have a lot of the criminal's DNA on them after the crime is committed.
DNA can be collected from various types of body materials, such as blood and hair.
