This potentiality of the virus molecule may occur in other kinds of protein molecules and may provide the fundamental clue to the stupendous variety of nature...
Viruses are protein molecules...
...showed. The biggest known, they weigh 17 million times as much as a hydrogen atom, nearly one million times as much as a molecule of water. Left by themselves they are inert. But in contact with living plant or animal material they multiply incessantly. Under some conditions the virus protein molecule changes its inner structure all by itself. It then causes a totally different disease...
...also explain inheritance of germ cells through the genes, units supposed also to be giant molecules. "In any case," said Dr. Stanley last week, "it now appears possible to list protein molecules along with living organisms such as bacteria, fungi and protozoa as infectious, disease-producing agents...
...photon (unit of radiation) is received in a living cell. The high energy carried on the photon swings the electrons of the cell up to correspondingly high energy levels which represent temperatures of 1,000,000°. This lasts for only some .00001 sec., but large protein molecules may be broken up, carbon dioxide and hydrogen given off, and water molecules in the cell oxidized to hydrogen peroxide. The cell may then sicken and die. If it is a cell in the reproductive germ plasm, a mutation or hereditary change may occur...
