Science is seldom advanced in isolation. Watson and Crick could not have arrived at their model of the helix without discovery of the structure of and how they are linked together, X-ray crystallography data, or biochemical analysis of the molar proportions of in double-stranded.

Correct question = What does the history behind the elucidation of secondary structure of DNA tell you about the role of the scientific community in advancing science? Were Watson and Crick solely responsible?

Explanation

The earlier discovery of nucleotide sequence and base pairing by Levene formed the basis of later discovery and formulation of double Helix DNA structure by Waston and Crick. Thus Levene work contributed to discovery of DNA double helix structure of Waston and Crick

In addition earlier work of Franklin on X-ray crystallography data, and comprehensive research on biochemical analysis of, molecular proportion of nucleotide by Chargaff, were another supporting bedrock on which Waston and Crick built their discovery of double helix structure of DNA.

Evidently most scientific discoveries were usually arrived at from the earlier work or discoveries, and rarely in isolation.
