DNA profiling, also known as genetic fingerprinting, is a powerful tool used in forensic science to identify individuals based on their unique genetic makeup. This technique analyzes specific regions of DNA that vary greatly among people, allowing forensic experts to match biological samples found at crime scenes such as blood, hair, or skin cells with potential suspects or victims.

DNA profiling has revolutionized criminal investigations by providing a reliable method for linking individuals to crime scenes or excluding them from suspicion. It is also used in identifying missing persons and victims of disasters. The accuracy and reliability of DNA evidence have made it an essential component of modern forensic science, helping to ensure justice through objective scientific analysis.
