...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...
...fourteenth year at Harvard, Doty has made other significant contributions in the area of protein synthesis. In addition to his work with DNA, he is currently examining the role of RNA, the other nucleic acid, which is believed to contribute to protein synthesis by controlling the unwinding of the genetic information carried...
...incubating ribonucleic acid (RNA) and protein from normal red cells with immature cells from victims of sickle-cell anemia, Cleveland's Dr. Austin S. Weisberger effected a crossover: the growing cells picked up the normal RNA and protein and, with it, the power to make normal hemoglobin. Cautiously, Dr. Weisberger hopes that similar methods may be developed for treating cancers of the blood...
...said his work indicates that it of three bases--the code-- acid that determine amino if the four kinds of bases in RNA are represented by the A, B, C, and D, ABC may result of one amino acid, ACB . The nucleic acid chain which these two amino acids...
