Amplification of short tandem repeats (strs) are two main dna tests widely used for dna fingerprinting other diagnostic methods exist, but they lack accuracy and precision. One of the more basic techniques in the microbiologist's toolkit is gel electrophoresis it's used to separate long molecules, like proteins, rna and dna from one another different organisms have different dna sequences, so electrophoresis can be used to identify organisms and for dna fingerprinting. Dna profiling (also called dna fingerprinting, dna testing, or dna typing) is the process of determining an individual's dna characteristics, which are as unique as fingerprints dna analysis intended to identify a species, rather than an individual, is called dna barcoding.
Dna fingerprinting is a chemical test that shows the genetic makeup of a person or other living things it's used as evidence in courts, to identify bodies, track down blood relatives, and to.

Genetic fingerprinting (also called dna testing, dna typing, or dna profiling) is a technique used to distinguish between individuals of the same species using only samples of their dna.
