DNA Fingerprinting :: Technology, Science

deoxyribonucleic acid FingerprintingIt is widely known that separately soulfulness has a DNA profile as unique as a fingerprint. Actually, over 99% of all 3 billion nucleotides in human DNA which we inherit from each parent are similar among all individuals. However, for every 1000 nucleotides that we inherit there is 1 spot of variation or polymorphism, in the population. These      DNA polymorphisms change the length of the DNA fragments produced by the digestion of restriction enzymes . The resulting fragments are called restriction fragments length polymorphisms. Gel cataphoresis can be used to separate and determine the coat of the RFLPs. The get hold of number and size of fragments produced by a specific restriction enzyme digestion varies from individual to individual.      DNA fingerprinting has proved valuable, not only for convicting felons and exonerating the innocent, but withal for establishing maternity or paternity and proving family relationships. More exotic uses include the identification of missing children in Argentina, soldiers killed in war, and even the body of Nazi atomic number 101 Joseph Mengele, the so-called "Angel of Death."The way it started          The fundamental techniques involved in heritable fingerprinting were discovered serendipitously in 1984 by inheritableist Alec J. Jeffreys of the University of Leicester in Great Britain season he was studying the gene for myoglobin, a protein that stores oxygen in vigor cells. He found that the myoglobin gene contains many segments that vary in size and composition from individual to individual and that have no apparent function. Jeffrey called these segments minisatellites because they were scurvy and they surround the part of the gene that actually serves as a genetic bluprint.
