There are regions on DNA that are made up of multiple copies of short repeating sequences of bases (for example TATT) which repeat a variable number of times depending on the individual. These regions, called âvariable number short tandem repeatsâ are what is looked at when performing STR analysis.The likelihood of two people having the same number of repeated sequences is extremely small, and becomes even smaller the more regions that are analyzed.hese regions, called âvariable number short tandem repeatsâ are what is looked at when performing STR analysis.
