What technique is identified by the acronym STR?

The technique identified by the acronym STR stands for Short Tandem Repeats. This method is widely used in forensic science, particularly in the analysis of DNA for criminal investigations. STR analysis involves examining specific locations on the DNA molecule where a short sequence of bases is repeated. The number of these repeats at various loci can vary significantly among individuals, providing a distinctive genetic profile.

STRs are highly valuable in forensic contexts because they are found in abundance throughout the human genome, and their variability enhances the ability to differentiate between individuals. This technique has become a standard in the field of DNA profiling due to its effectiveness in generating reliable results that can help link suspects to crime scenes, identify victims, or establish familial relationships. Understanding STRs is crucial for anyone involved in criminal investigations or forensic biology, as they represent a cornerstone of modern genetic analyses in these fields.
