WebApr 3, 2024 · DNA profiling is an extremely powerful tool for solving crimes. If the evidence contains sufficient DNA from just one or two people, forensic experts can often produce a clear DNA profile of the person or people who left it. That profile, sometimes called a genetic fingerprint, can provide a solid lead in a case. WebSTRs and forensics [ edit] In the United States, 13 different autosomal STR loci are used as a basis of analysis for forensic purposes.
