Johannes Friedrich Miescher (13 August 1844 – 26 August 1895) was a Swiss physician and biologist. He was the first scientist to isolate nucleic acid in 1869. Miescher also identified protamine and made several other discoveries. Miescher had isolated various phosphate-rich chemicals, which he called nuclein (now nucleic acids), from the ...
The Swiss scientist Friedrich Miescher discovered the "nuclein", in 1868. Later, he raised the idea that it could be involved in heredity. [3]Nucleic acid was, partially, first discovered by Friedrich Miescher in 1869 at the University of Tübingen, Germany.
A major milestone in molecular biology was the discovery of the structure of DNA. This work began in 1869 by Friedrich Miescher, a Swiss biochemist who first proposed a structure called nuclein, which we now know to be (deoxyribonucleic acid), or DNA. [15]
1869: Friedrich Miescher discovers a weak acid in the nuclei of white blood cells that today we call DNA. In 1871 he isolated cell nuclei, separated the nucleic cells from bandages and then treated them with pepsin (an enzyme which breaks down proteins). From this, he recovered an acidic substance which he called "nuclein". [1]
DNA extraction. The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other ...
American biochemist at Tulane University, a pioneer in clinical chemistry and the measurement of protein in biological fluids. Zacharias Dische (1895–1988). American biochemist of Ukrainian-Jewish origin, who discovered metabolic regulation by feedback inhibition. Henry Berkeley Franks (Hal) Dixon (1928–2008).
Kossel was an important influence on and collaborator with other important researchers in biochemistry, including Henry Drysdale Dakin, Friedrich Miescher, Edwin B. Hart, and his professor and mentor, Felix Hoppe-Seyler. Kossel was editor of the Zeitschrift für Physiologische Chemie (Journal of Physiological Chemistry) from 1895 until his death.
