DNA fingerprinting

DNA fingerprinting is a scientific technique used to identify individuals based on their unique genetic makeup. It analyzes specific regions of DNA that vary greatly among people. By comparing these patterns, scientists can determine relationships, identify suspects in criminal cases, establish paternity, or even study ancestry. The process involves collecting a sample, such as blood or saliva, and then using laboratory methods to reveal an individual’s distinct DNA profile. This technology has revolutionized forensic science and has important applications in medicine, heritage research, and law enforcement.
