DNA fingerprinting

DNA is the hereditary material presents in all the cells of the body. This molecule presents some characterizes characteristics, as a variable number of tandem repeats (VNTR), which are uniquely present in each individual. This is a key in the development of some techniques, in this case DNA fingerprinting. This procedure method has simple steps that we will review in this work, as well as, its applications. DNA fingerprinting technique has become an important tool for scientific research, it is being used in fields like as forensic investigations and parentage testing, moreover how this technique has revolutionized and evolved in areas as Anthropological genetics, botany and zoology
