The tetrahelix model of DNA
Buckminster Fuller proposed the tetrahelix model as a physical and conceptual analogue to the DNA double helix, suggesting it could explain fundamental biological patterning and the complexity of DNA. The tetrahelix is a structure of interconnected tetrahedra that forms a helical column, with ten tetrahedra completing one full 360° turn. Fuller believed this structure's characteristics, such as its rigidity and nested helical patterns, mirrored aspects of DNA's structure and function.
