Forensics: DNA Profiling

DNA profiling, developed in 1984 at Leicester University, revolutionized forensic science by enabling the identification of individuals through unique DNA patterns. Initially, the RFLP technique was used, requiring large DNA samples. However, PCR technology later allowed for more efficient and accurate profiling from smaller samples. DNA profiling is now a crucial tool in criminal justice, helping to convict criminals, eliminate suspects, and exonerate the innocent.
