After several failed attempts at model building, including a three-stranded version Watson and Crick worked out the structure of DNA using wire models of atoms and molecules similar to those used in many chemistry classes today.
The double helix – twisted-ladder structure of deoxyribonucleic acid (DNA) is well known today but the many that led to the final structure were disposed off by the Cavendish Laboratory in Cambridge.
A budding modernist sculptor got one of the earlier models. He added a dinosaur head biting into a piece of rock-steak. It was the cornerstone of his future success.
