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.
Francis Harry Compton Crick OM FRS [3] [4] (8 June 1916 – 28 July 2004) was an English molecular biologist, biophysicist, and neuroscientist.He, James Watson, Rosalind Franklin, and Maurice Wilkins played crucial roles in deciphering the helical structure of the DNA molecule.

1972 – The DNA composition of chimpanzees and gorillas is discovered to be 99% similar to that of humans. 1973 – Stanley Norman Cohen and Herbert Boyer perform the first successful recombinant DNA experiment, using bacterial genes. [6] 1974 – Scientists invent the first biocement for industrial applications.
By 1957 he has identified the first DNA polymerase. [5] The enzyme was limited, creating DNA in just one direction and requiring an existing primer to initiate copying of the template strand. Overall, the DNA replication process is surprisingly complex, requiring separate proteins to open the DNA helix, to keep it open, to create primers , to ...
Leroy E. Hood's laboratory at the California Institute of Technology announced the first semi-automated DNA sequencing machine in 1986. [56] This was followed by Applied Biosystems ' marketing of the first fully automated sequencing machine, the ABI 370, in 1987 and by Dupont's Genesis 2000 [ 57 ] which used a novel fluorescent labeling ...
The intervening sequences in the RNA strand are first spliced out so that only the RNA segment left behind after splicing would be translated to polypeptides. [62] 1994: The first breast cancer gene is discovered. BRCA I was discovered by researchers at the King laboratory at UC Berkeley in 1990 but was first cloned in 1994.
The discovery was announced on February 28, 1953; the first Watson/Crick paper appeared in Nature on April 25, 1953. Sir Lawrence Bragg , the director of the Cavendish Laboratory , where Watson and Crick worked, gave a talk at Guy's Hospital Medical School in London on Thursday, May 14, 1953, which resulted in an article by Ritchie Calder in ...
