Detailed explanation-1: -Only one year after Hershey and Chase performed these experiments, James Watson and Francis Crick determined the three-dimensional structure of DNA. This discovery enabled investigators to put together the story of how DNA carries hereditary information from cell to cell.

Detailed explanation-2: -Watson and Crick brought together data from a number of researchers (including Franklin, Wilkins, Chargaff, and others) to assemble their celebrated model of the 3D structure of DNA. In 1962, James Watson, Francis Crick, and Maurice Wilkins were awarded the Nobel Prize in Medicine.

Detailed explanation-3: -The Nobel Prize in Physiology or Medicine in 1962 was awarded to James Watson, Francis Crick and Maurice Wilkins for their discovery of the molecular structure of DNA, which helped solve one of the most important of all biological riddles.

Detailed explanation-4: -In “A Structure of Deoxyribose Nucleic Acid, ” Watson and Crick described DNA as a double helix that contained two long, helical strands wound together. In their model, each DNA strand contained individual units called bases, and the bases along one DNA strand matched the bases along the other DNA strand.
