Which King's College physicist showed Watson an X-ray image of DNA in January 1953?
Answer
Maurice Wilkins
78 public questions with answers, drawn from the well. How many can you answer?
This James Watson and Francis Crick trivia hub focuses on the scientists, evidence, collaborators, publications, and ideas behind the discovery of DNA’s double-helix structure. Questions revisit the X-ray evidence shown at King’s College, the diagram drawn for their 1953 paper, and the 1951 meeting in Bologna where Watson encountered DNA research.
The set also explores Crick’s birthplace near Northampton, the Francis Crick Institute in London, the initials used in the landmark paper, its DOI, and Crick’s 1994 book on consciousness. It suits science students, biology teachers, history-of-science enthusiasts, and quiz teams. The questions highlight both the famous partnership and the wider network of researchers whose work shaped molecular biology.

Good questions cover the double helix, DNA X-ray diffraction, Rosalind Franklin, Maurice Wilkins, the 1953 Nature papers, and the scientists’ later work. Examples include identifying who showed Watson an important X-ray image, naming the illustrator of the DNA diagram, and recalling Crick’s book on consciousness.
This is generally advanced science and history trivia. Basic questions about DNA’s double helix may be familiar to biology students, but details about collaborators, conferences, publication bylines, institutes, and book titles require more specialized knowledge. It works especially well for classroom review and academic quiz rounds.
In 1953, James Watson and Francis Crick proposed a model for DNA’s molecular structure as a double helix. Their model explained how paired bases fit within the structure and suggested a mechanism for copying genetic information. It relied on experimental evidence and insights from several other researchers.
Researchers at King’s College London produced crucial X-ray diffraction evidence. Maurice Wilkins showed Watson an image associated with this work, while Rosalind Franklin’s experiments and analysis were especially important to understanding DNA’s dimensions and helical form. Their contributions were central to the context surrounding the 1953 model.
Their landmark 1953 paper was titled “Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid.” It was published in Nature on April 25, 1953. The brief paper introduced the double-helix model and became one of the most influential publications in modern biology.
