Rosalind franklin (1920- 1958), a British physicist and biochemist, laid the foundation for the discovery of DNA double helix structure in the study of DNA structure, which had an important impact on the development of modern biology and medicine.

Although her work played a key role in the discovery of DNA structure, Franklin was not recognized in history. Her achievement lies not only in discovering the structure of DNA, but also in striving for more opportunities and equality for female scientists. Her achievements and contributions made her an admirable scientist and pioneer.

life experience

First, when I was a girl, my curiosity awakened.

Rosalind franklin was born in a wealthy Jewish family in London. When she was young, she showed great interest in science and mathematics. Her curiosity and thirst for knowledge laid the foundation for her to become an outstanding scientist in the future. This also qualifies her for Oxford University.

Franklin studied physics and chemistry at Oxford University, and received his doctorate at Cambridge University. At school, she showed outstanding academic ability. In addition, Franklin also learned many languages, which is very helpful for her future international research.

Second, start your career and move towards Excellence

In the first stage of her career, rosalind franklin devoted herself to the study of crystallography, involving the structure of coal, the crystallography of various materials and the cell structure.

During this period, she became an expert in X-ray crystallography. He also works in some well-known research institutions and universities in Britain, including University College London and King's College. The experience at this stage laid the foundation for her to study the structure of DNA.

Third, DNA exploration, creating a new era.

195 1 year, Franklin was invited to join the biochemical research group of King's College London. Here, she began an in-depth study of DNA structure. She used X-ray crystallography to photograph DNA at high resolution. Together with Gosling, we found two types of DNA, type A and type B, and put forward the X-ray diffraction diagram of type A DNA.

Franklin's research laid the foundation for human beings to understand the structure and function of DNA. This result provides extremely important data for other researchers, and finally provides evidence for the double helix structure of james watson and francis crick.

Fourth, precious heritage and immortal influence.

Although her work played a key role in the discovery of DNA structure, Franklin was not recognized at that time. 1953, james watson and francis crick did not disclose Franklin's contribution in their papers on DNA structure. Among them, Watson described Franklin as a "female pedant" in the book "Double Helix" and described her as an uncooperative figure.

It was not until several years after her death that her works were finally widely recognized and praised. Her achievement lies not only in discovering the structure of DNA, but also in winning more opportunities and lower scores for female scientists. Her achievements and contributions made her an admirable scientist and pioneer.
