The First Discovery of DNA Few remember the man who discovered the "molecule of life" three-quarters of a century before Watson and Crick revealed its structure 来自 Semantic Scholar 喜欢 0 阅读量: 4 作者: R Dahm 摘要: On February 26, 1869, in the old university town of T?bingen in ...
The very first cell in a living being is formed when egg and sperm get mingled. At that point DNA molecule renders the entire genetic code to be used for the formulation of cells forever in that creature. These cells divide and replicate themselves perfectly to construct the body structure. ...
The structure ofDNAwas elucidated in 1953, but it was actually discovered in 1868 in a small laboratory in Germany by a Swiss scientist named Friedrich Miescher. When I ask most people the simple question, “Who discoveredDNA?”, I get one of two answers: “I don’t know” or “Watson ...
Who discovered the modern structure of DNA? Who discovered the monomers of nucleic acids? What is DNA polymerase responsible for? Why did the invention of PCR make DNA fingerprinting possible? Who discovered prokaryotic cells? What contributions did Rosalind Franklin make towards Watson and Crick's ...
His discovery: DNA. His name: Friedrich Miescher. In this article, the authors try to find answers to the question why-despite the fact that virtually everyone nowadays knows DNA-hardly anyone remembers the man who discovered it. In the history of science, the discovery of DNA was a seminal...

"She contributed more than any other player to solving the structure of DNA. She must be considered a co-discoverer," Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the "Dark Lady of DNA", Franklin is ...
