Dna Forensics And The Human Genome - 2744 Words

Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Phillips, 2008). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem repeats are also the same for all people, but the number of repetitions is highly variable. Before this discovery, a drop of blood at a crime scene could only reveal a person’s blood type, plus a few proteins unique to certain people. Now DNA f orensics can expose a person’s gender, race, susceptibility to diseases, and even propensity for high aggression or drug abuse (Phillips, 2008). More importantly, the certainty of DNA evidence is extremely powerful in court. Astounded at this technology’s almost perfect accuracy, the FBI changed the name of its Serology Unit to the DNA Analysis Unit in 1988 when they began accepting requests for DNA comparisons (Lewis, 1989). There are thirteen standard tandem repeats used in modern forensics, andShow MoreRelatedDna Forensics And The Human Genome2746 Words   |  11 Pages DNA Forensics Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence.

These DNA molecules are made up of two strands. Every strand is composed of four nucleotide bases: adenine, thymine, guanine, and cytosine. Complementary strands are paired in certain ways. Cytosine always pairs with guanine and adenine always pairs with thymine. The human genome holds about 3 billion base pairs, found in the chromosomes. Each of the 46 chromosomes are composed of thousands of genesRead MoreThe Uses Of Dn Dna Fingerprinting1486 Words   |  6 PagesTran Mr. Tucker AP Biology 26 August 2015 The Uses of DNA: DNA Fingerprinting Sir Alec Jeffreys’ 1984 discovery of DNA fingerprinting in England has revolutionized the criminal justice system by enabling legal entities to determine innocence or guilt of a suspect to a much higher level of accuracy(Butler).
