Discuss the arguments for and against developing a genetic finger print profile for each member of society.
Discuss the arguments for and against developing a genetic finger print profile for each member of society.
DNA finger printing is the method for isolating and making images of sequences of DNA. The technique was first developed in 1984 by a British scientist, Alec Jeffreys, after he noticed the existence of certain sequences of DNA, called minisatellites, that do not contribute to the function of a gene but are repeated within the gene and in other genes of a DNA sample. Jeffreys determined that each living thing has a unique pattern of these minisatellites, with the exception of identical twins, just like each person has a unique finger print.
But unlike a conventional fingerprint, which occurs only on the fingertip and can be altered by surgery, a DNA fingerprint is the same for every cell, tissue and organ of a person and cannot be altered. As a consequence, DNA fingerprinting is fast becoming the primary and most reliable method of identifying and distinguishing between individuals.
But how reliable is it?
Concerns rose about sample contamination, faulty preparation techniques and the credibility of interpretations, as human error could lead to false results. In addition, DNA fingerprinting is often carried out in private laboratories that may not follow uniform testing standards and quality controls. Also a large-scale research to confirm the uniqueness of DNA fingerprinting test results has not been conducted.
