Explanation:
DNA fingerprinting is a test to identify and evaluate the genetic information called DNA (deoxyribonucleic acid) in person’s cell. DNA fingerprinting is a form of identification based on sequencing specific non-coding portions of DNA that are known to have a high degree of variability from person to person. These sections are known as Tandem repeats. The test is used to determine whether a family relationship exists between two people, to identify organisms causing a disease, and to solve cirmes.
