In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure.
May 16, 2020 · Learn about the double helix, the shape of DNA that holds the genetic code of life. Discover how it was discovered by Watson and Crick, and its features, such as complementary base pairing, antiparallel orientation and grooves.
Learn what a double helix is and how it describes the structure of DNA molecules. Find out who discovered the double helix and how they won a Nobel Prize for their work.
Oct 9, 2019 · The immediate reception of the double-helix model was surprisingly muted 9, perhaps because there was no obvious mechanism to explain its role in protein synthesis. In a landmark talk in 1957 ...

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 ...
Learn how the double helix of DNA was discovered by Watson, Crick, Franklin, and others through X-ray crystallography and biochemical analysis. Explore the properties and components of the DNA molecule and its antiparallel, right-handed helix.
Learn how Watson and Crick built on the work of previous scientists to propose the structure of DNA as a three-dimensional double helix in 1953. Explore the history of DNA research from Miescher to Levene to Chargaff and beyond.
