STR (Short Tandem Repeat)

Short Tandem Repeats (STRs) are small sections of DNA where a short sequence of bases (like "AG" or "TC") repeats multiple times in a row. These regions are highly variable among individuals, making them useful for identifying people in forensic science, paternity tests, and genetic studies. The number of repeats at specific STR locations differs from person to person, providing a unique genetic fingerprint. STR analysis involves measuring these repeat lengths to compare genetic profiles efficiently and accurately.
