Short Tandem Repeats (STRs)

Short Tandem Repeats (STRs) are small, repetitive sequences of DNA where certain patterns of two to six base pairs are repeated multiple times in a row. These sequences vary greatly among individuals, making them useful for identifying genetic differences. STR analysis is commonly used in forensic science for DNA profiling, helping to link or exclude suspects in criminal cases. Additionally, STRs are important in paternity testing and genetic studies, as they can provide insight into familial relationships and population genetics. Their variability and abundance in the genome make them valuable tools in biological research and law enforcement.
