...know who reviewed Disney's Polly anna [May 9], but the poor dear must have an awfully acid stomach, else how could he belch so? He would certainly have been revolted by my daughter's prayer, "God bless Walt Disney, he loves little children so and makes such beautiful things for them." I understand these are the sentiments of children around the world. I for one wish to thank Mr. Disney...
...each of them contains a genetic "instruction code" that tells it how to develop into a particular sort of creature, ranging from a bacterium to a man. In the case of higher animals, the cell's instructions are carried by long, coiled-up molecules of DXA (deoxyribonucleic acid). In the instance of some viruses, which are the simplest of organisms, the code is found in RNA (ribonucleic acid), which is less complicated...
...structure is extremely simple. All it has is a core of coiled-up RNA surrounded by a cylindrical jacket made of protein molecules. Tsugita and Fraenkel-Conrat first stripped off the jacket by use of a protein-dissolving chemical. Then they treated the naked RNA with nitrous acid, which is known to affect the RNA's code-carrying bases. After the nitrous acid had. acted, the RNA was enabled to clothe itself in a new coat of protein. This made it a functioning virus again, and when it was injected into a tobacco plant, it multiplied in the plant...
Changing the Code. The report from Tsugita and Fraenkel-Conrat went little farther than that. But Nobel Prizewinning Wendell M. Stanley, head of Berkeley's Virus Laboratory, believes that the original action of the nitrous acid was to change one kind of RNA base into another...
...variety of softening agents. Also -and most important from the public-health standpoint-it shows that addition of chlorine and fluorides has no effect on heart-artery disease. One clue: the more alkaline the water, the greater the protective effect on human arteries. This may be because more acid waters, which build up "rust in the pipes" to plague plumbers, also pick up impurities that create "rust" in the body's pipes...
