Helical Structure

A helical structure is a spiral or winding shape, like a spring or a corkscrew. In biology, many important molecules, such as DNA and certain proteins, adopt helical forms that allow them to be compact yet flexible, enabling functions like carrying genetic information or structural support. This shape results from specific chemical interactions that cause the molecule to twist around an axis, creating a stable, repeating pattern. The helix’s geometric properties help molecules perform their roles efficiently within cells, combining strength, flexibility, and functional versatility.
