Solving Crimes with DNA and Electrophoresis
DNA analysis has become a cornerstone of modern forensic science. Because every individual (except identical twins) has a unique DNA profile, scientists can use DNA evidence from crime scenes to help identify suspects or eliminate individuals from suspicion. One common method for comparing DNA samples is gel electrophoresis, a technique that separates DNA fragments based…
