The double helix model of DNA (deoxyribonucleic acid) consists of two intertwined strands. These strands are made up of nucleotides, which themselves consist of three component parts: a sugar group, a phosphate group, and a base. The sugar and phosphate groups combined form the repeating ‘backb...
When Watson and Crick puzzled out DNA's structure, everyone understood that science was poised to take a new direction. Watson and Crick knew that DNA controlled the creation of proteins, the building blocks of organisms, but did not understand how it worked. They and other researchers in the...

Watson and Crick published a landmark 1953 paper in the journalNature. In that paper, they proposed the iconic double-helix model of DNA as we now know it, with sugar-phosphate sides and rungs made up of A-T and G-C base pairs. They also suggested that, based on their proposed struc...
