DNA Profiling
Modern DNA technology methods have rapidly transformed the field of forensics. Forensics is the scientific analysis of evidence for crime scene investigations and other legal proceedings. The most important application of forensics is DNA profiling. DNA profiling is the analysis of DNA samples to determine whether they came from the same individual. First, DNA samples are isolated from the crime scene, suspects, victims, or other evidence. Second, selected markers from each DNA sample are copied many times, producing a large sample of DNA fragments. And last, the amplified DNA markers are compared, providing data about which samples are from the same individual. -Biology book pg. 242
