WebInfo. In 1953, Watson and Crick published a paper: A Structure for Deoxyribose Nucleic Acid. Based on available data from X-ray diffraction patterns and 3D conceptualization through model building, Watson and Crick proposed that DNA is a double helix - a twisted ladder - with two phosphate-based backbones and "runged" nucleotides that pair.
