SCIENCE – The use of DNA profiling

DNA profiling, also known as DNA fingerprinting, is a technique used to identify individuals based on their unique DNA characteristics. It has become an invaluable tool in forensic and genetic research, allowing scientists to identify suspects in criminal investigations and trace the ancestry of individuals. Let’s dive into the various uses of DNA profiling. Criminal Investigations DNA profiling is perhaps best known for its use in criminal investigations. The technique was first developed in the mid-1980s by British geneticist Alec Jeffreys, who discovered that specific regions of an individual’s DNA could be used to create a unique genetic “fingerprint.” The first use of DNA profiling in a criminal investigation occurred in 1986 when it was used to catch the killer of two young girls in the UK. Since then, DNA profiling has become an invaluable tool in forensic investigations, allowing law enforcement officials to identify suspects and exonerate innocent individuals. One of the primary advantages of DNA profiling in criminal investigations is its accuracy. Because each individual’s DNA is unique, it is possible to use DNA evidence to identify suspects with a high degree of accuracy. In addition, DNA profiling can be used to link suspects to crime scenes, even […]
