Profile

Rosalind Franklin (192-1958) British physicist and biochemist laid the foundation for the discovery of the double helix structure of DNA in the research of DNA structure, which has 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 first woke up

Rosalind Franklin was born in London, and the children of a wealthy Jewish family showed great interest in science and mathematics when she was young. Her curiosity and thirst for knowledge laid the foundation for her to become an outstanding scientist in the future. It also qualified her to enter Oxford University.

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

Second, starting a career, the road to 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 research on the structure of DNA.

third, DNA exploration, creating a new era

In p>1951, 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 technology to photograph DNA with high resolution. Together with Gosling, they discovered two types of DNA: type A and type B, and put forward that the X-ray diffraction pattern of type A DNA

Franklin laid a foundation for human to understand the structure and function of DNA. The results provide extremely important data for other researchers, and finally provide evidence for the double helix structure of james watson and francis crick.

IV. Precious legacy, immortal influence

Although her work played a key role in the discovery of DNA structure, Franklin was not recognized at that time. In 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 his book "Double Helix" and described her as an uncooperative figure.

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