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.
The Double Helix: A Personal Account of the Discovery of the Structure of DNA is an autobiographical account of the discovery of the double helix structure of DNA written by James D. Watson and published in 1968. It has earned both critical and public praise, along with continuing controversy about credit for the Nobel award and attitudes ...
February 15 – Linus Pauling proposes a DNA triple helix structure, [1] which is rapidly shown to be incorrect. 25 April 1953: the DNA double helix is first formally described. February 28 – Francis Crick and James Watson enter The Eagle, Cambridge, for a pub lunch announcing "We have discovered the secret of life." [2]
The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
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 ...
Friedrich Miescher (1844–1895) discovered a substance he called "nuclein" in 1869. Somewhat later, he isolated a pure sample of the material now known as DNA from the sperm of salmon, and in 1889 his pupil, Richard Altmann, named it "nucleic acid". This substance was found to exist only in the chromosomes.
The remains of a teenager found more than 50 years ago have been identified through advanced DNA technology as a young woman who went missing from Portland, Oregon State Police said.
