Walter Jennings Jones
Walter Jennings Jones (April 28, 1865 – February 28, 1935) was an American biochemist and a professor at Johns Hopkins University who was among the early investigators of the composition of the nucleic acids including the presence of nucleotides, sugar and phosphate. He also noted the presence of thermostable enzymes that could break the nucleic acids by breaking the inter-nucleotide bonds. He published his results in the 1920 book ''Nucleic Acids: Their Chemical Properties and Physiological Conduct''. Early life Jones was born in Baltimore to Zeanette Jane (née Bohen) and Levin Jones, both devout Methodists. His father was a ship chandler of his business at the Light Street Wharf in Baltimore. His father died when he was thirteen. Jones's middle name was after a physician friend of the family and he rarely used it. He was educated at local schools, and joined the City College, Baltimore in 1879 and graduated in the spring of 1884. He joined Johns Hopkins University in 1884 ...

Joseph Raphael De Lamar
Joseph Raphael De Lamar (September 2, 1843 – December 1, 1918) was a prominent mine owner and operator in the western United States and Canada, as well as a financier and speculator, from the late 1870s until his death in 1918. Early life De Lamar was born in Amsterdam to Maximiliaan de la Mar (1814–1847) and Johanna Teune (1816–1867). His father, a banker in Amsterdam, died when Joseph had just turned four years old. In search of adventure, De Lamar stowed away aboard a Dutch vessel heading to the West Indies. When he was discovered, he was put to work without pay as assistant to the cook. De Lamar worked as a seaman until he was twenty, when he became master of a ship, and three years later received a captain's command. He visited many of the world's ports and acquired an education through his observations in foreign countries. He was attracted to underwater work, including salvage which was profitable owing to the American Civil War, so he abandoned the merchant ser ...

Wittenberg University Faculty
Wittenberg ( , ; Low Saxon: ''Wittenbarg''; meaning ''White Mountain''; officially Lutherstadt Wittenberg (''Luther City Wittenberg'')), is the fourth largest town in Saxony-Anhalt, Germany. Wittenberg is situated on the River Elbe, north of Leipzig and south-west of Berlin, and has a population of 46,008 (2018).

Pancreatic Ribonuclease Family
Pancreatic ribonuclease family (, ''RNase'', ''RNase I'', ''RNase A'', ''pancreatic RNase'', ''ribonuclease I'', ''endoribonuclease I'', ''ribonucleic phosphatase'', ''alkaline ribonuclease'', ''ribonuclease'', ''gene S glycoproteins'', ''Ceratitis capitata alkaline ribonuclease'', ''SLSG glycoproteins'', ''gene S locus-specific glycoproteins'', ''S-genotype-assocd. glycoproteins'', ''ribonucleate 3'-pyrimidino-oligonucleotidohydrolase'') is a superfamily of pyrimidine-specific endonucleases found in high quantity in the pancreas of certain mammals and of some reptiles. Specifically, the enzymes are involved in endonucleolytic cleavage of 3'-phosphomono nucleotides and 3'-phosphooligonucleotides ending in C-P or U-P with 2',3'-cyclic phosphate intermediates. Ribonuclease can unwind the RNA helix by complexing with single-stranded RNA; the complex arises by an extended multi-site cation-anion interaction between lysine and arginine residues of the enzyme and phosphate groups of t ...

Phoebus Levene
Phoebus Aaron Theodore Levene (25 February 1869 – 6 September 1940) was a Russian born American biochemist who studied the structure and function of nucleic acids. He characterized the different forms of nucleic acid, DNA from RNA, and found that DNA contained adenine, guanine, thymine, cytosine, deoxyribose, and a phosphate group. He was born into a Litvak (Lithuanian Jewish) family as ''Fishel Rostropovich Levin'' in the town of Žagarė in Lithuania, then part of the Russian Empire, but grew up in St. Petersburg. There he studied medicine at the Imperial Military Medical Academy (M.D., 1891) and developed an interest in biochemistry. In 1893, because of anti-Semitic pogroms, he and his family emigrated to the United States and he practiced medicine in New York City. Levene enrolled at Columbia University and in his spare time conducted biochemical research, publishing papers on the chemical structure of sugars. In 1896 he was appointed as an Associate in the Pathol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetranucleotide Hypothesis
The tetranucleotide hypothesis of Phoebus Levene proposed that DNA was composed of repeating sequences of four nucleotides. It was very influential for three decades, and was developed by Levene at least into the 1930s, and the diagram at the right illustrates the view of Levene and Tipson. In 1940, at the time of Levene's death, Bass wrote in his obituary As a result of Levene’s work we have an exact concept of the structures of these huge molecules, probably the most complex biological materials whose architectural picture has been reconstructed. In that form there is an implication that the four bases are present in equal amounts in DNA, and small variations in the experimental values were assumed to be the result of experimental error. However, Erwin Chargaff showed that the four frequencies were not equal, with variations consistent between different studies.
