DNA fingerprinting is currently based on the analysis of autosomal short tandem repeats (STRs). STRs are DNA segments that are typically found in noncoding regions of genome and are composed of repeating units of 3-5 nucleotides sequence patterns. Because of their high mutation rate. 

One of the major obstacles to molecular analysis of genomic DNA is the immense size of the molecules involved. The discovery of a special group of bacterial enzymes, called restriction endonucleases (restriction enzymes), which cleave double-stranded DNA into smaller, more manageable fragments, has opened the way for DNA analysis. Because each enzyme cleaves DNA at a specific nucleotide sequence, restriction enzymes are used experimentally to obtain precisely defined DNA segments called restriction fragments.
