Rosalind Franklin is best known for her contribution to unraveling the We may share your information with third-party partners for marketing purposes. However, it was researchers James Watson, Francis Crick, and Maurice Wilkins who The relationship between Wilkins and Franklin was frosty at best. At King's College London, Rosalind Franklin obtained images of DNA using Franklin's images allowed James Watson and Francis Crick to create The relationship between Wilkins and Franklin was unfortunately a poor.

Bernal as "among the most beautiful X-ray photographs of any substance ever taken. With this knowledge, they were able to publish their model of the DNA double helix. If she had, there would have been an almighty explosion," said Glynn.

However, it was her continued perseverance in the face of professional and personal challenges that has earned her the label of a female icon. Pursuing a new area of research After spending 2 unhappy years at King's College, Franklin moved to Birkbeck College in London to study viruses.

Franklin pictured in a laboratory at Birkbeck College in National Library of Medicine "I think many people were taken aback by her personality and authority, and the entire situation that transpired between Franklin and Wilkins would be enough to drive many people out of science altogether," Ellen Elliott, Ph.

At the time, knowledge of molecular biology was still in its infancy, as Prof.

But intragedy hit. During a work-related visit to the United States, Franklin began experiencing swelling and pain in her abdomen. She was soon diagnosed with ovarian cancer. Over the following year, Franklin underwent numerous surgeries and treatments for her cancer. She continued her work throughout, even applying for a 3-year research grant so that her team could investigate the structure of the polio virus - the first animal virus to be crystallized.

After her passing, two members of her research team - John Finch and Aaron Klug - published a paper detailing the structure of the polio virus, which they dedicated to Franklin. Even in the face of death, Franklin put science first. As Bernal said in an obituary for Franklin, she was "the perfect example of a single-minded devotion to research.

Of course, Franklin was a scientist during a time when sexism was at its peak. She often spoke to friends and family about her frustration at being excluded from the senior common room at King's College, which was out of bounds for all women.

However, Franklin herself said that she never felt that gender bias held back her research. For many researchers, Franklin is an inspiration not solely because she was a successful female scientist in a male-dominated field, but because of the challenges she overcame to reach her goals - particularly when it came to workplace politics.

For instance, Jim Watson and Franklin did not get along well during her time at King's College, but they actually developed a close relationship later on when they were both studying the structure and function of viruses. I think it takes a really strong person to accept and move beyond past disagreements, and this further highlights how incredibly important science was to Franklin.

An example of how collaboration can yield success In an age where research networks are increasingly becoming the norm and a requirement for many scientific funding bodies, the ability to work collaboratively is a key feature of success for many of today's scientists.

Franklin's career is a good example of how personal differences can get in the way of this, as her relationship with Wilkins showed. Using enzymes that broke down specific cell components, Avery and his team showed by a process of elimination that DNA, not protein, was the transforming principle. Physicists had also contributed to this debate - for instance, Erwin Schr? Simple crystals such as sodium chloride cannot carry genetic information because their ions are arranged in a periodic pattern.

Proteins had been the obvious candidate for the aperiodic crystal, with the amino acid sequence providing the code. Research to determine the structure of DNA took on an added urgency although final confirmation of its central role was still to come, from experiments carried out by Alfred Hershey and Martha Chase in the US in the early s. Avery gave us the first text of a new language, or rather he showed us where to look for it.

I resolved to search for this text.

Rosalind Franklin :: DNA from the Beginning

Each species differed in the amount of A, C, G and T - but within the species, the proportions of each are identical, no matter which tissue the DNA is extracted from. It was just what might be expected for a molecule that is the biological signature for the species. Although Chargaff himself appears to have made little direct use of his findings, the idea of base-pairing A with T, C with G was to be a crucial step in piecing together the three-dimensional structure of DNA.

The final phase of solving the puzzle of the DNA structure relied on X-ray crystallography. ByWilliam Astbury, a student of William Bragg who, with son Lawrence, had invented the technique in had X-ray pictures of DNA, but they were hard to interpret. The late s saw three separate groups working intensively on the DNA structure. He produced more X-ray pictures, using makeshift apparatus the like of which is hard to imagine nowadays.

InWilkins was joined by Rosalind Franklin, a British physical chemist who already had an international reputation for her work on the X-ray crystallography of coals. These led her to the idea that maybe the DNA molecule was coiled into a helical shape.

Linus Pauling, the US chemist, and author of The nature of the chemical bond, began to think along similar lines. After all, Pauling had already discovered helical motifs in protein structures. Around this time, Francis Crick - with a background in maths and physics, and the younger James Watson, with expertise in the molecular biology of phage viruses that infect bacteria, then used as a laboratory tool for genetic studiesjoined forces at the Cavendish Laboratory in Cambridge, intent on cracking the DNA structure themselves, using a model building approach.

They had the idea that the structure of DNA had to allow the molecule to copy itself during cell division, so that an exact replica of its code - which, again, was embedded in the structure - could pass into each new cell. A visit to the Cavendish by Chargaff in prompted the further thought that perhaps the sequence of bases might represent the genes in a chemical code.

Meanwhile, Pauling published a paper on the DNA structure, but it contained a major error he put the phosphate groups on the inside. The entry of this scientific giant into the race spurred Crick and Watson to greater efforts, while Wilkins and Franklin were not really getting on well and were making little progress with DNA.

Previous studies had used the A form, which contains less water and had led to images that were hard to analyse. This picture, by contrast, was beautifully simple and seemed to point clearly to a helical structure for the molecule. As Watson puts it in his famous memoir: Model building - using metal plates for the nucleotides and rods for the bonds between them - now began in earnest.

The final clue came from another visitor to the Cavendish, the American chemist Jerry Donohue, who pointed out how hydrogen bonding allows A to bond to T and C to G. This allows a double helical structure for DNA, where the two strands have the bases on the inside, paired up, and the phosphates on the outside. The true beauty of the model that Crick and Watson built was that the structure immediately suggested function. As they hinted, in their Nature paper: The DNA molecule is self-replicating as was proved by experiments a few years later because it can unwind into two single strands.

Each base then attracts its complementary base, by hydrogen bonding, so that two new double helices are assembled. Crick, Watson and Wilkins went on to win the Nobel prize for their work in Franklin died of cancer at the age of 37 in
