Short Tandem Repeat (STR) Analysis

Nuclear DNA (nucDNA) analysis targets the DNA found within the nucleus of the cell and is unique to each individual except identical twins. NucDNA is inherited one half from the mother and one half from the father. Locations (loci) within nucDNA have repeating segments of base pairs called short tandem repeats or STRs. The number of repeated segments varies among humans. DNA analysis using STR technology is useful for the identification of biological materials found in multiple types of forensic cases.
