Can DNA unlock secrets hidden in our cells?
Imagine a detective needs to prove a suspect's presence at a crime scene without direct evidence.
DNA fingerprinting compares tiny genetic markers unique to each person, like a biological barcode. This technique helps match biological samples found at a crime scene to a suspect.
Example
If a drop of blood is found at the scene, DNA profiling can match it to the suspect's unique genetic markers.
Remember this
DNA fingerprinting can conclusively link a suspect to a crime scene through their unique genetic code.
