It is thought to have been distorted by magnetic torsion into the shape of two connected spirals, known popularly as a double helix, akin to the shape of DNA.
James Michael Creeth (3 October 1924 – 15 January 2010) was an English biochemist whose experiments on DNA viscosity confirming the existence of hydrogen bonds between the purine and pyrimidine bases of DNA were crucial to Watson and Crick's discovery of the double helix structure of DNA.
Rudolf Signer (*17 March 1903 Herisau † 1 December 1990 Gümlingen ) contributed to the discovery of the DNA double helix.

Watson and Crick (who later won the Nobel Prize for their double-helix model) originally considered a triple-helix model, as did Pauling and Corey, who published a proposal for their triple-helix model in the 1953 scientific journal Nature, as well as fellow scientist Fraser.
Crick comments on various aspects of the DNA double helix discovery and gives a qualified endorsement to the 1987 television movie Life Story with Jeff Goldblum as Jim Watson and Tim Piggott-Smith as Francis Crick.
