Helix

A helix is a three-dimensional spiral shape, similar to a spring or the structure of a spiral staircase. In nature, DNA is commonly described as a double helix, which means it has two entwined strands that form a twisted ladder-like structure. Helices can be found in various contexts, including biology, architecture, and even in everyday objects like screws and coils. This shape is significant because it allows for stability and efficient functioning, enabling structures to maintain their form while also engaging in movement, such as the curling of a ribbon or the winding of a vine.
