What started as a hidden structure inside the cell became one of the biggest turning points in modern science. In this episode of The Unlocked Podcast, we walk through Rosalind Franklin’s role in revealing the structure of DNA, how that opened the door to sequencing, genomics, and gene editing, and why wearables now bring biology into everyday life through sleep, recovery, stress, and performance data.

We begin with the early mystery of heredity, when scientists still did not fully know what carried biological information from one generation to the next. From there, we move into Franklin’s X ray diffraction work and Photograph 51, the image that helped bring DNA’s structure into view. Once that structure became clear, biology changed.

We then move into the genomic era and break down how science progressed from structure, ...
