Mitochondrial DNA
Mitochondrial DNA was discovered in the 1960s by Margit M. K. Nass and Sylvan Nass by electron microscopy as DNase-sensitive threads inside mitochondria, and by Ellen Haslbrunner, Hans Tuppy and Gottfried Schatz by biochemical assays on highly purified mitochondrial fractions.
Science and technology in Switzerland
Friedrich Miescher was a Swiss physician who was the first researcher to isolate and characterize Nucleic acid (DNA). Today, a research institute in Basel (the Friedrich Miescher Institute, FMI) is named after him. Emil Theodor Kocher (Nobel Prize in Physiology or Medicine 1909) was known for his work in the physiology, pathology and surgery of the thyroid. The neurologist Walter Rudolf Hess (Nobel Prize in Physiology or Medicine 1949) mapped the areas of the brain that were responsible for the control of several vital bodily functions. The biochemist Werner Arber (Nobel Prize in Physiology or Medicine 1978) is known for his discovery of restriction endonucleases which are essential for all modern biotechnology. The Swiss born Edmond H. Fischer (Nobel Prize in Physiology or Medicine 1992) discovered how reversible phosphorylation works as a switch to activate proteins. Rolf M. Zinkernagel (Nobel Prize in Physiology or Medicine 1996) is famous for his work on the immune system.
