The painting's title is a portmanteau of the name of Dalí's wife, Gala Dalí, and deoxyribonucleic acid (DNA). It is a tribute to Francis Crick and James D. Watson, who are credited with determining the double helical structure of DNA in 1953. The painting is in the collection of the Salvador Dalí Museum in St. Petersburg, Florida. [1]
The DNA double helix was discovered in 1953 [4] (with further details in 1954 [5]) based on X-ray diffraction images of DNA (most notably photo 51, taken by Raymond Gosling and Rosalind Franklin [6]) as well as base-pairing chemical and biochemical information.
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 ...

Bind to ssDNA and prevent the DNA double helix from re-annealing after DNA helicase unwinds it, thus maintaining the strand separation, and facilitating the synthesis of the new strand. Topoisomerase: Relaxes the DNA from its super-coiled nature. DNA gyrase: Relieves strain of unwinding by DNA helicase; this is a specific type of topoisomerase ...
In DNA double helix, the two strands of DNA are held together by hydrogen bonds. The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. The purines are adenine and guanine ...
Life Story (known as The Race for the Double Helix in the United States) is a 1987 television historical drama which depicts the progress toward, and the competition for, the discovery of the structure of DNA in the early 1950s.
From the DNA double helix model, it was clear that there must be some correspondence between the linear sequences of nucleotides in DNA molecules to the linear sequences of amino acids in proteins. The details of how sequences of DNA instruct cells to make specific proteins was worked out by molecular biologists during the period from 1953 to 1965.
