Rosalind Franklin joined King's College London in January 1951 to work on the crystallography of DNA. By the end of that year, she established two important facts: one is that phosphate groups, which are the molecular backbone for the nucleotide chains, lie on the outside (it was a general consensus at the time that they were at the inside); and the other is that DNA exists in two forms, a ...

Building on her manuscripts, she discovered that form A DNA had antiparallel backbones, which supported the double helical structure of DNA. [86] She did this through identification of the space group for DNA crystals. This would go to help Watson and Crick decide to look for DNA models with two antiparallel polynucleotide strands.
A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics. In the following years, chemists developed techniques for sequencing both nucleic acids and proteins, while many others worked out the relationship between ...
Each of the scientists published their own unique contributions to the discovery of the structure of DNA in separate articles, and all of the contributors published their findings in the same volume of Nature. These classic molecular biology papers are identified as: Watson J. D. and Crick F. H. C. "A Structure for Deoxyribose Nucleic Acid".
DNA analysis sheds new light on the fate of the men in Sir John Franklin’s doomed Arctic voyage to explore the Northwest Passage, according to the latest research. ... The scientists found the ...
Since the dawn of time, humans have asked what makes us so special. After a recent study conducted at the University of California, humans may now have a glimpse into the answer to that age old ...
In April 2023, scientists, based on new evidence, concluded that Rosalind Franklin was a contributor and "equal player" in the discovery process of DNA, rather than otherwise, as may have been presented subsequently after the time of the discovery.
