Who really discovered DNA? 1953 – James Watson and Francis Crick propose a model for the structure of the DNA molecule. They publish the structure in the scientific journal Nature and suggest that the structure indicates DNA’s function. James Watson and Francis Crick © Getty Images.
The discovery of DNA is one of our greatest scientific achievements – these are scientists who led to its discovery. Kath Nightingale. Published: April 10, 2020 at 12:00 am. 1.
This discovery enabled investigators to put together the story of how DNA carries hereditary information from cell to cell. Indeed, the experiments connecting heredity and...

The discovery of the structure ofDNAhas lead to major accomplishments and medical advancements. Not only was the discovery essential to the progress of the field of genetics, but also impacted society and technology beneficially. The experiments done by Erwin Chargaff, Rosalind Franklin, James Watson and Francis Crick led to the discovery of the st...
The understanding of genetics and DNA has increased in the past ten years due to increased technological advancement and scientific discoveries. However, in order for this to be possible, the foundation of genetics and the definition of DNA had to be established first. Geneticsis the study of heredity and how organisms inherit information from one ...
The discovery of the structure of DNA was an essential breakthrough for the field of genetics and its progression throughout history. Determining more about the structure impacted society on a global level due to the fact that every country was or would be struggling with disease at some point and could benefit from increased knowledge regarding th...
Erwin Chargaff was the first of the geneticists to start the process of accumulation of information regarding the structure of DNA. He started his experiments in 1944, where he was curious about the composition of DNA in different organisms. At this point, he was aware of the postulations and findings of both Aristotle and Mendel when it came to ge...
Another scientist who contributed to the discovery of the structure of DNA was Rosalind Franklin. Franklin conducted her experiments in 1951 using X-ray crystallography(Braun, 2011). She was aware of the base pair rules that had just been established by Chargaff and wanted to expand on them by determining more information about the structure of DNA...
The last scientists that officially culminated all of the information discovered in past experiments to establish the structure of DNA were James Watson and Francis Crick. These two scientists are credited with discovering the structure of DNA as it is known today. Instead of actually performing an experiment however, they used the information they...
Chargaff, Franklin, Watson, and Crick were able to jumpstart the era of modern genetics by discovering the basis of how organisms know how to function, or the molecule of DNA. The most prominent example of how this has affected modern genetics is through the human genome project(Burn, 2007). This project has been able to determine the sequence of n...
