Paul M. Doty, professor of Chemistry, has recently succeeded in separating and recombining the two strands of bases which comprise the helical structure of DNA...
...Crick, visiting professor of explained his latest genetics to a spellbound, overflow of more than 400 at yesterday. Crick and J.D. Watson Professor of Biology, are the of the Watson-Crick model of acid DNA, considered one outstanding achievements...
...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...
...later described the present and future in the study of the DNA chain. He did not rule out the possibility that his area of biological sciences could also "open wide" as the physical sciences have done...
...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...
