WebIn April 1953, Watson and Crick published their model of the DNA double helix in Nature. [3] The same issue additionally included papers by Wilkins and colleagues, [4] [5] each describing different aspects of the molecular structure of DNA. In 1962, James Watson, Francis Crick, and Maurice Wilkins were awarded the Nobel Prize in Physiology and ... WebAs new nucleotides are added to a strand of DNA or RNA, the strand grows at its 3’ end, with the 5′ phosphate of an incoming nucleotide attaching to the hydroxyl group at the 3’ end of the chain. This makes a chain with each sugar joined to its neighbors by a set of bonds called a phosphodiester linkage. Properties of DNA
