The discovery of the DNA was made by the Swiss physician Friedrich Miescher. It was first called as a “nuclein” because it resides in the nuclei of a cell. This reconstruction of the first ever model of the DNA molecule contains some of the original parts used by Crick and Watson in 1953. Their breakthrough made it possible to finally understand both how organisms pass on their genes, and how the workings of cells are governed. This now-familiar structure is still at the heart of huge scientific endeavours.
And with genome sequencing becoming ever cheaper, we’re only going to become more familiar with it.
