DNA fingerprinting is a method used to identify living things based on samples of their DNA. DNA Fingerprinting is a way to identify a certain individual, rather than simply identifying a species or a particular trait. Expert Answer: DNA fingerprinting is a method of identifying the DNA by locating the differences in the arrangement of nucleotides in those specific regions of the DNA sequence which are repeated several times. Meaning: DNA of an individual carries some specific sequence of bases, which do not carry any information for protein synthesis.

DNA Fingerprinting 1. A. The following are some of the main applications of DNA fingerprinting, DNA fingerprinting is widely used to find out the real biological parent or offspring in paternity-maternity disputes. High school students learned from their lecture classes in biology that the deoxyribonucleic acid or the DNA is the genetic material enclosed inside the nucleus of a cell. DNA fingerprinting is used to find out the biological father or mother or both, of the child, in case of disputed parentage. These sequence show high degree of polymorphism and form the basis of DNA fingerprinting. Paternity disputes have been resolved thanks to this method. DNA fingerprinting is the process by which forensic scientists identify a subject by using his DNA. DNA fingerprinting is very useful in such an application because it provides the police with an exact match of who left evidence at the crimescene. Methods of DNA Fingerprinting.
