Nucleic acid double helix
In
molecular biology
, the term
double helix
refers to the structure formed by double-stranded molecules of
nucleic acids
such as
DNA
. The double
helical
structure of a nucleic acid complex arises as a consequence of its
secondary structure
, and is a fundamental component in determining its
tertiary structure
. The term entered popular culture with the publication in 1968 of
The Double Helix: A Personal Account of the Discovery of the Structure of DNA
, by
James Watson
