James Watson and Francis Crick are famous for their discovery of the double - helix structure of DNA. How did they achieve this discovery? A. By working independently without any communication. B. By stealing the results from other scientists. C. By collaborating closely and using data from ...
Erwin Chargaff was one of a handful of scientists who expanded on Levene's work by uncovering additional details of the structure of DNA, thus further paving the way for Watson and Crick. Chargaff, an Austrian biochemist, had read thefamous 1944 paper by Oswald Avery and his colleaguesat Roc...
helical structure of DNAscientific discoveryThe development of X-ray diffraction photography was central to the discovery of the helical structure of DNA in 1953. Unfortunately the story of how this technique was developed receded into the background as subsequent attention focused on the moment of ...
What the Double Helix (1953) Has Meant for Basic Biomedical Science THE ARTICLE published by Watson and Crick in 19531 was the landmark pointer to our contemporary model of DNA as a macromolecular structure. This lay on a w... J Lederberg - 《Annals of the New York Academy of Sciences》...
The Double Helix Crucial to the discovery of the double helix by James Watson and Francis Crick was, in the first place, their involvement with the spatial structure of DNA; what was the reason for their interest? At that time, the scientific world was s... R Hausmann - Springer Netherlan...

The development of the DNA theory of inheritance culminated in the publication of the molecular structure of DNA 60 years ago. This paper describes this development, beginning with the discovery of DNA as a chemical substance by Friedrich Miescher in 1869, followed by its basic chemical analysis ...
A FEW YEARS BACK, THE 50TH anniversary of the discovery of the structure of the DNA double helix by biologists James D. Watson and Francis H. C. Crick was grandly celebrated. Last month marked a less celebrated anniversary: 50 years since the discovery of the RNA double helix. It was in...

Methionine residue was shown to play roles in lipid bilayer interaction, and support the alpha-helix conformation in polypeptides26,27,28,29. Proline residues provide rigidity to the peptide secondary structure, and possibly help reduce the energetic cost during membrane permeation30. It is important...
