Presents an analysis of nucleic acid. Uses a large model of the tobacco mosaic virus to explain its structure. Demonstrates how a virus can be reconstituted from nucleic acid and protein molecules. Discusses the recent discovery of the alteration of nucleic acid to form mutations of the original virus. Concludes with a theory which may account for the way in which genetic information is stored in nucleic acid and then translated into a specific protein structure.
