Detailed explanation-1: -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-2: -With the aid of illustrations, Watson and Crick state that their model of DNA consists of two helical strands twisted around each other in a double helix. Each strand, the authors explain, contains a chain of repeating units called nucleotides, where each nucleotide contains a sugar, a phosphate group, and a base.
Detailed explanation-3: -They used X-ray crystallography to identify that DNA is made up of two strands wrapped around each other to produce a double-helical structure. Along with X-ray crystallography, they also made use of Chargoff principles.
