2005年2月15日 · Miescher had obtained the first crude purification of DNA. He further examined the properties and composition of this enigmatic substance and showed that it fundamentally …

2021年9月1日 · In 1871, the Swiss physiological chemist Friedrich Miescher published the results of a detailed chemical analysis of pus cells, in which he showed that the nuclei of these cells …

The story of genetics typically omits the original discovery of the molecular nature of DNA: Friedrich Miescher's 1869 discovery of the substance he christened “nuclein”. The article …

2013年4月22日 · Miescher isolated a material rich in phosphorus from the cells and called it nuclein. He found nuclein in other types of cells as well, including salmon sperm. In the early …

In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist …

Through extensive purification of cell nuclei, Miescher successfully isolated a novel organic substance he termed ‘nuclein’. Nuclein distinguished itself from other cell-derived organic …

Since he had isolated it from the cells' nuclei he named it nuclein, a name preserved in today's designation deoxyribonucleic acid. In subsequent work Miescher showed that nuclein was a …

Although few people realize it, 1869 was a landmark year in genetic research, because it was the year in which Swiss physiological chemist Friedrich Miescher first identified what he called...

2007年9月28日 · With his purest preparation of nuclein, Miescher determined the P 2 O 5 content in salmon sperm nuclein to be 22.5% of its total mass (Miescher 1872c), a figure very close to …
