Which 1953 Nature paper by Wilkins, Stokes, and Wilson accompanied Watson and Crick's DNA paper?

The 1953 Nature paper by Wilkins, Stokes, and Wilson was titled “Molecular Structure of Deoxypentose Nucleic Acids.” It appeared in the same 25 April 1953 issue as James Watson and Francis Crick’s landmark paper proposing the DNA double helix.

The Wilkins, Stokes, and Wilson paper reported X-ray diffraction work on DNA. Their observations provided evidence for a helical structure and helped support the emerging picture of DNA as an organized, repeating molecular assembly. The paper was one of several closely connected contributions published under the broad theme of nucleic-acid structure.

Rosalind Franklin and Raymond Gosling also published a companion paper in that issue, presenting important X-ray diffraction evidence. Watson and Crick’s paper supplied the molecular model, while the King’s College researchers supplied experimental observations that constrained and supported it.

The title is easy to confuse with Watson and Crick’s “A Structure for Deoxyribose Nucleic Acid.” The similar wording reflects the terminology of the period: “deoxypentose nucleic acid” was an older name for what is now usually called deoxyribonucleic acid, or DNA.
