In 1953, when they created the model of DNA double helix, it was regarded as an enormous achievement in fields of molecular genetics and biochemistry. For their work Crick, Watson, and Wilkins were awarded the Nobel Prize in 1962.

James Watson and his British colleague Francis Crick discovered the double helix structure of DNA. For this fundamental finding James, Francis and Maurice Wilkins were awarded the Nobel Prize for Physiology or Medicine in 1962.

It is a common misconception that James Watson and Francis Crick discovered DNA in the 1950s. In reality, DNA was discovered decades before. It was by following the work of the pioneers before them that James and Francis were able to come to their ground-breaking conclusion about the structure of DNA in 1953. The story of the discovery of DNA begins in the 1800s….

During the early years of Levene's career, neither Levene nor any other scientist of the time knew how the individual nucleotide components of DNA were arranged in space; discovery of the sugar-phosphate backbone of the DNA molecule was still years away.

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.

One of the ways that scientists have elaborated on Watson and Crick's model is through the identification of three different conformations of the DNA double helix. In other words, the precise geometries and dimensions of the double helix can vary.

Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.

(The term nuclein was later changed to nucleic acid and eventually to deoxyribonucleic acid, or DNA.) Miescher's plan was to isolate and characterize not the nuclein (which nobody at that time realized existed) but instead the protein components of leukocytes (white blood cells).

DNA discovered was in 1953. The Deoxyribonucleic acid was discovered in 1953.
