Question

How can DNA be used to help solve a crime

Answer 1

Using DNA found at the crime scene, you can identify who was present at the scene, and find suspects of your crime in the form of fingerprints, skin samples, or hair. Sometimes, the DNA can point directly to the criminal.

Answer 2

If DNA is found at a crime scene it can help locate people that were at the crime scene. If the criminal has committed crimes before their DNA will already be in the police system. If not they can take samples from suspects and pinpoint who committed the crime.
