Alec Jeffreys. After finishing his doctorate, he moved to the University of Amsterdam, where he worked on mammalian genes as a research fellow, [15] and then to the University of Leicester in 1977, where in 1984 he discovered a method of showing variations between individuals' DNA, inventing and developing genetic fingerprinting.
1982: The U.S. Food and Drug Administration (FDA) approved the release of the first genetically engineered human insulin, originally biosynthesized using recombination DNA methods by Genentech in 1978. [54] Once approved, the cloning process lead to mass production of humulin (under license by Eli Lilly & Co.).
Using these x-rays and information already known about the chemistry of DNA, James D. Watson and Francis Crick demonstrated the molecular structure of DNA in 1953. [ 25 ] [ 26 ] Together, these discoveries established the central dogma of molecular biology , which states that proteins are translated from RNA which is transcribed by DNA.
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

Phil Hanawalt (born 1931), US geneticist, discovered DNA repair replication; Anita Harding (1952–1995), UK neurologist, first mitochondrial DNA mutation in disease; G. H. Hardy (1877–1947), British mathematician, formulated basic law of population genetics; Henry Harpending (1944–2016), US anthropologist and human population geneticist
After moving to nearby Emeryville, they began projects involving the new biotechnology industry, primarily the cloning and expression of human genes, but also the development of diagnostic tests for genetic mutations. In 1976 a DNA polymerase [12] was isolated from T. aquaticus. It was found to retain its activity at temperatures above 75 °C.
Mendel, known as the "father of modern genetics," chose to study variation in plants in his monastery's 2 hectares (4.9 acres) experimental garden. [26] Mendel was assisted in his experimental design by Aleksander Zawadzki while his superior abbot Napp wrote to discourage him, saying that the Bishop giggled when informed of the detailed ...
