Genetic fingerprinting refers to the process of identifying individuals based on their DNA, which is different from person to person (only monozygotic twins have identical DNA). About 99.9% of DNA is identical in every human - genetic fingerprinting takes advantage of these minute differences. Genetic fingerprinting takes advantage of differences called Variable Number Tandem Repeats (VNTR), in particular Short Tandem Repeats (STR). These are sections of DNA in which small segments are repeated. The number of times the segment is repeated is different among people. If enough VNTRs are studied, it can be used to distinguish ...
