Detailed explanation-1: -Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.
Detailed explanation-2: -At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model.
Detailed explanation-3: -Rosalind Franklin’s X-ray diffraction patterns of DNA molecules rendered the important clue that DNA has the structure of a double helix.
Detailed explanation-4: -On 6 May 1952, at King´s College London in London, England, Rosalind Franklin photographed her fifty-first X-ray diffraction pattern of deoxyribosenucleic acid, or DNA.
Detailed explanation-5: -Answer: Watson and Crick defined DNA as a double helix with two long helical strands twisted together in their paper titled A Structure of Deoxyribose Nucleic Acid. According to them, each DNA strand has discrete units known as bases. The bases along one DNA strand match the bases along the other DNA strand.
