How is DNA Fingerprinting Used in Forensic Science?

DNA fingerprinting, also known as DNA profiling, is a crucial tool in forensic science for identifying individuals based on their unique genetic make-up. In the USA, DNA fingerprinting is extensively used to solve criminal cases by matching crime scene evidence with suspects or convicted individuals. This technology relies on detecting specific DNA sequences, known as markers, that vary from person to person. By comparing these markers, forensic scientists can determine whether two DNA samples are from the same person or related individuals. Overall, DNA fingerprinting plays a significant role in providing accurate and reliable evidence for criminal investigations.
