A closer look at “Rosalind Franklin's Overlooked Calculations: How Photo 49 Paved the Way for DNA's Double H”, exactly as the source publishes it. A new study reveals that Rosalind Franklin, the pioneering crystallographer, had already deduced critical structural details of DNA from an earlier X-ray image, 'Photo 49,' before capturing the iconic 'Photo 51.' This challenges long-held narratives that minimized her contribution to the discovery of the double helix. Franklin's meticulous analysis of Photo 49 allowed her to calculate key features such as the helical pitch and diameter, which were later confirmed by Photo 51.
The findings underscore that Franklin was far closer to solving DNA's structure than previously acknowledged, and that her work was foundational for James Watson and Francis Crick's model. The study, published in a peer-reviewed journal, highlights the importance of recognizing overlooked contributions of women in science.
