Paul M. Doty, professor of Chemistry, Michael Litt, tutor in Biochemical Sciences, and Julius Marmur, research fellow in Biology and Chemistry, have used sound waves in studying desoxyribose nucleic solid, believed to be "the essential hereditary material of all living organisms, except some viruses...
...subtle methods of organic chemistry, he synthesized, one by one, a wide range of delicate biochemicals, including vitamins E and B1. His research led him to the nucleus of the cell, where the all-powerful genes are stored. These mysterious chemicals, which control heredity and growth, are made of nucleic acids, and Sir Alexander worked out methods of studying their complex structure. By use of his methods, it may soon be possible to synthesize nucleic acids, perhaps even molecules that will grow and reproduce. For coming close to the secret of life, Sir Alexander won his Nobel Prize...
...Baltimore, Dr. Cornelius P. Rhoads (TIME, June 27, 1949), director of the Sloan-Kettering Institute for Cancer Research, told how five years ago chemical research was directed into all kinds of areas-hormones, alkylating agents. Today, cancer chemists are concentrating on nucleic acid, which all cells need in order to live. If the cancer cells' supply of nucleic acid can be poisoned, the cells will...
...Dallas this week, an encouraging advance on the drug front was jointly announced by Sloan-Kettering, the Mellon Institute and Parke, Davis & Co. Their newest drug: "D.O.N." (for 6-diazo-s-oxo-l-norleucine), which effectively inhibits the formation of nucleic acid in mouse cancer cells, but causes negligible harm to healthy cells...
...Fraenkel-Conrat and Williams then mixed the two parts of the virus together, made the solution slightly acid and held it just above freezing point for 24 hours. At the end of this period, the protein molecules had rearranged themselves on the nucleic acid cores. When tested on tobacco plants, the virus proved infectious. It grew and multiplied in the green leaves, producing the characteristic spots of tobacco mosaic disease...
