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 ...
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.
Johannes Friedrich Miescher (13 August 1844 – 26 August 1895) is a Swiss physician and biologist. He was the first scientist to isolate nucleic acid in 1869. Miescher also identified protamine and made several other discoveries.
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.
Now, scientists have used ancient DNA collected from the casts that have been made to better understand the Pompeii residents and their origins. What they found alters history that’s been ...
Each of the scientists published their own unique contributions to the discovery of the structure of DNA in separate articles, and all of the contributors published their findings in the same volume of Nature. These classic molecular biology papers are identified as: Watson J. D. and Crick F. H. C. "A Structure for Deoxyribose Nucleic Acid".
A former Colorado Bureau of Investigation DNA scientist appeared in court Thursday to face criminal charges over data tampering that authorities said raises questions about the validity of more ...
