WebA helix(/ˈhiːlɪks/) is a shape like a corkscrewor spiral staircase. It is a type of smoothspace curvewith tangent linesat a constant angleto a fixed axis. Helices are important in biology, as the DNAmolecule is formed as two intertwined helices, and many proteinshave helical substructures, known as alpha helices.
