What are VNTR's used for in forensics?

Variable Number Tandem Repeats (VNTRs) are used in forensics for DNA profiling and identification in criminal investigations. They consist of short sequences of DNA that are repeated variable times in different individuals, making them highly polymorphic. By analyzing VNTR patterns, forensic scientists can create a unique DNA profile for individuals, which can be compared to DNA found at crime scenes to help establish connections to suspects or victims. This technique is valuable in solving cases and exonerating the innocent.
