A conformation or shape describing a structure that typically consists of two matching helices intertwined about a common axis, such as the structure of the DNA molecule, which is made of two linear strands held together in opposite direction through chemical bonds, and which has become twisted into a helix (that is a three-dimensional spiral similar to the shape of a railing on a spiral staircase).


The double-helix model of DNA structure was first conceptualized by James D. Watson and Francis Crick in 1953.
