Final answer:
In addition to Watson and Crick, Linus Pauling and Maurice Wilkins made important contributions to the discovery of the three-dimensional structure of DNA.
Step-by-step explanation:
In addition to Francis Crick and James Watson, Linus Pauling and Maurice Wilkins made important contributions to the discovery of the three-dimensional structure of DNA.
Linus Pauling had discovered the secondary structure of proteins using X-ray crystallography, and Maurice Wilkins' lab employed researcher Rosalind Franklin, who used X-ray diffraction methods to study DNA's structure. Watson and Crick were able to piece together the puzzle of the DNA molecule by studying Franklin's data.
