WebWatson and Crick model of DNA. 1. DNA molecule consists of two polynucleotide chains. 2. These chains form a double helix structure with two strands which run anti-parallel to one another. 3. Nitrogenous bases in the centre are linked to sugar-phosphate units which form the backbone of the DNA. WebWatson-Crick Model of DNA: In 1953, J.D.Watson (an American biologist) and F.H.C. Crick (a British Physicist) proposed the three-dimensional model of physiological DNA (i.e. B-DNA) on the basis of X-ray diffraction data of DNA obtained by Franklin and Wilkins. For this epoch- making discovery, Watson, Crick and Wilkins got Nobel Prize in ...
