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 nucleosome is the basic structural unit of dna packaging in eukaryotes the structure of a nucleosome consists of a segment of dna wound around eight histone proteins and resembles thread wrapped around a spool.
