...this spring will have an opportunity to hear the Nobel-winning scientist lecture in person on DNA, for Watson is a regular member of the teaching staff of that course. In addition to his pedagogical activities, Watson is still deeply involved in research, primarily on the mechanisms of protein synthesis in the cell...
...does nothing but its job; if other delicate compounds are present, it leaves them strictly alone. Most Wallerstein enzymes are made by specially nourished cultures of bacteria or fungi. Today they treat skins in place of dog manure, keep bottled beer from looking cloudy by digesting the haze of protein that forms when it is chilled. But newer uses are constantly developing. Dr. Beckhorn is working on enzymes to turn cornstarch into syrups specially suited for baking or candy making, and on enzymes that can be injected by multiple hypodermic needles into whole sides of beef, the dose carefully calculated...
Moolten's paper-- The Effect of Thyroxin on Nucleic Acid and Protein Metabolism in House Thyrotropic Pituitary Tumors"--was one of six presented at the 22nd annual undergraduate assembly of the Harvard Medical Society...
...result," Dr. Wacker said, "was a doubling of the DNA [deoxyribonucleic acid] in the nucleus of the cell [a process that precedes normal cell division] although the RNA [ribonucleic acid] content of the cell was markedly reduced along with protein and zinc...
...This indicates," Dr. Wacker pointed out, "that there is mitotic arrest and a block in both RNA and protein synthesis resulting from zinc deficiency--a condition that is not reversed when other trace metals [iron, manganese, copper, magnesium and calcium] metabolic precursors or metabolites, are added to the nutrient solution in which the organism is grown...
