...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...
...viruses are basically cubic or helical in structure. They also reveal that viruses may have an exquisitely complex symmetry around as many as five axes, and contain hundreds of submolecules, each of which may have a hollow hexagonal structure. Chemical tests show whether viruses have cores of ribonucleic acid (RNA) or deoxyribonucleic acid (DNA), and whether they have enzymes or fats in their coats...
...Huppert began with the generally accepted fact that a normal cell contains chemically coded information-in ribonucleic acid (RNA) or deoxyribonucleic acid (DNA)-which determines how it reproduces itself. But, he suggested, ''a cell may acquire some wrong genetic information,' perhaps through the entry of a virus into the cell. The virus need not necessarily multiply within the cell; all that is necessary is for a piece of the virus' RNA or DNA to be substituted for part of the cell's normal nucleic acid...
