American molecular biologist, geneticist, and zoologist (born 1928) For other people named James Watson, see James Watson (disambiguation). James Watson Watson in 2012 Born James Dewey Watson (1928-04-06) April 6, 1928 (age 96) Chicago, Illinois, U.S. Education University of Chicago (BS ...
Bryan Sykes (1947–2020), British human geneticist, discovered ways to extract DNA from fossilized bones; Jack Szostak (born 1952), Anglo-US geneticist, worked on recombination, artificial chromosomes, and on telomeres. He was awarded a Nobel Prize for his work on telomeres.
The DNA double helix structure proposed by Watson and Crick was based upon "Watson-Crick" bonds between the four bases most frequently found in DNA (A, C, T, G) and RNA (A, C, U, G). However, later research showed that triple-stranded, quadruple-stranded and other more complex DNA molecular structures required Hoogsteen base pairing.
A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics. In the following years, chemists developed techniques for sequencing both nucleic acids and proteins, while many others worked out the relationship between ...
Francis Sellers Collins ForMemRS (born April 14, 1950) is an American physician-scientist who discovered the genes associated with a number of diseases and led the Human Genome Project. He served as director of the National Institutes of Health (NIH) in Bethesda, Maryland , from 17 August 2009 to 19 December 2021, serving under three presidents.
Franklin was a physical chemist who made pivotal research in the discovery of the structure of DNA, known as "the most important discovery" in biology. [1] [2] DNA itself had become "life's most famous molecule". [3] While working at the King's College London in 1951, she discovered two types of DNA called A-DNA and B-DNA. Her X-ray images of ...
Human DNA recovered from remains found in Europe is revealing our species’ shared history with Neanderthals. The trove is the oldest Homo sapiens DNA ever documented, scientists say.
1989: Thomas Cech discovered that RNA can catalyze chemical reactions, [60] making for one of the most important breakthroughs in molecular genetics, because it elucidates the true function of poorly understood segments of DNA. 1989: The human gene that encodes the CFTR protein was sequenced by Francis Collins and Lap-Chee Tsui.
