Imagine being arrested for a crime you didn't commit, a serious crime, maybe one in which you could lose your life if you're convicted. Imagine that a series of everything that can go wrong does--maybe you were in the vicinity of the crime or maybe you were home alone at the time of the crime with no one to vouch for you, maybe you knew the victim, maybe you didn't like him, perhaps you argued, maybe an over eager eyewitness mistakenly puts you at the scene. Imagine your relief knowing that your DNA will be compared to some found at the crime scene.
