Rosalind Franklin

Rosalind Franklin, completely Rosalind Elsie Franklin (born July 25, 1920, London, London, born in London, April 16, 1958 London), used for encoding British scientist genetic information known for DNA molecular structure discovery An integral part of the chromosome to be done. Franklin also provides new insight into the structure of viruses and helps lay the foundation for structural virology.

Franklin studied at St. Paul Girls' College before studying physics chemistry at Cambridge University in Newham. After graduating in 1941, she received a scholarship from physics chemistry research from the University of Cambridge. However, the progress of World War II has changed the way of action. In addition to serving as an air raid sheriff in London, she abandoned fellowship in 1942 to work for the British Coal Utilization Research Association. Chemistry of carbon and coal used in the situation war But she could apply this research to doctor thesis and in 1945 got a doctorate from Cambridge University. From 1947 to 1950, she studied X-ray diffraction techniques in collaboration with Jacques Melering of the National Chemistry Institute in Paris. This study led to her study on structural changes caused by the formation of graphite in heated carbon - it is worth the coking industry.

In 1951, Franklin joined the Biophysics Laboratory at King's College London as a researcher. So, she applied X - ray diffraction to DNA research. When she started studying at King's College, I do not know much about the chemical composition and structure of DNA. But she quickly discovered the density of the DNA and, more importantly, confirmed that the molecule is present in a helical structure. She laid the foundation for a clearer X-ray map of DNA molecules and in 1953 James Watson and Francesco Rick suggested that the DNA structure is a double helix polymer and the helix consists of two entangled DNA strands.

From 1953 to 1958, Franklin worked at the Institute of Crystallography at the Birkbeck University in London. So she finished studies on coal and DNA and started a project on the molecular structure of tobacco mosaic virus. Her collaboration has shown that the viral ribonucleic acid (RNA) is embedded in its protein rather than its central cavity and that the RNA is a single helical helix rather than the double helix found in bacterial viral DNA . Higher biology In 1958, Franklin ceased participating in state-of-the-art DNA research due to the early death of cancer.

Rosalind Franklin - (UK, 1920-1958) Rosalind Franklin uses X - ray crystallography to observe the structure of DNA. Watson and Crick proposed a double-stranded helical structure of DNA molecules using her data. As the Nobel Prize could only be awarded to living people, she was unable to win the Nobel Prize when Watson and Click were officially approved in November Medical Physiology Award in 1962. She is also using X-ray crystallography to study the structure of the tobacco mosaic virus. Alice Hamilton - (USA, 1869-1970) Alice Hamilton is a chemist and a doctor who directed the first government committee to investigate the industrial hazards in the workplace, such as exposure to hazardous chemicals. Because of her work, the law protects employees from occupational hazards. In 1919, she became the first female teacher at Harvard Medical School.

Rosalind Elsie Franklin was born on July 25, 1920 in a wealthy and sociable family in London, England. Her father was investment banker Ellis Arthur Franklin and her mother was lawyer's daughter Muriel Frances Waley. Rosalind is the second of five children. She works hard. Once, when asked to choose a book as a school award, she chose Arthur Eddington 's new 1935 scientific approach. Topics include quantum theory, elementary particle energy, and group theory - a fairly advanced reading for 15 years old. Rosalind felt her fate lies in physics.

The real tragedy of Rosalind Franklin 's life is not that she was robbed of the Nobel prize, instead science was robbed of Franklin' s other 20 - 40 years of research. She is still a source of inspiration for many female scientists, including myself, and her work on DNA structure is important for modern molecular biology and genomics research. Without the pioneering research of Rosalind Franklin it may take another 10 years to fully realize the DNA double helix.
