Description: Titles are: BETWEEN LIVING AND THE NON-LIVING. Shows how various viruses fit between the largest non-living molecules and the smallest unit of life. Uses models to explain the organization of various kinds of molecules and viruses. Reviews the first experiment in which a virus was isolated, purified and crystallized. Concludes with a discussion on the importance of viruses in the understanding of all living matter. CANCER. Discusses the relationship between viruses and cancer; explains how viruses can cause cancer in animals and why it is believed they may be responsible for cancer in humans. Summarizes the important known facts about viruses, and indicates directions in which future research in virology might take. GIANT MOLECULES. Presents an analysis of the structure of viruses and how they are similar. Explains how an electron microscope works. Uses film clips of experiments to demonstrate the isolation, mutation, and preparation of viruses; discusses the difference between viruses. HOW A VIRUS KILLS. Explains how a virus invades a cell and uses animation and microcinematography to show how a virus enters a cell, stops its normal functions and reproduces. Tells how new viruses are made and describes their method of escape to infect other cells. Discusses possible methods of controlling virus diseases. KILLERS AND CARCINOGENS. Dr Harry Rubin tells the story of such viral diseases as smallpox and rabies. Discusses the development of vaccination, and explains how a normal cell, when attacked by a virus which eventually is capable of killing it, may be analyzed. Analyzes types of viruses which cause cancers in animal cells. Discusses various virus diseases, viral diseases, and explains the need to guard cells. Shows how virus cultures can be grown and used for inoculation and describes some of the procedures which may be developed to cure virus diseases. THE STUFF OF LIFE. Discusses the degree to which viruses possess properties of life. Discusses the genetic content of chromosomes and viruses; relates the information discovered from the study of chromosomes and viruses to life creation and formation. Uses microcinematography to show how viruses are formed within viruses can be formed and identified. THREAD OF LIFE. Presents an analysis of nucleic acid, using a large model of the tobacco mosaic virus to explain its structure. Demonstrates how a virus can be reconstituted from nucleic acid and proteins, and discusses protein formation and discovery in the alteration of nucleic acid to form. Presents a theory which may account for the way in which genetic information stored in nucleic and then translated into a specific protein structure. VIRAL GENES. Presents an analysis of bacteriophages and how they may change. Explains why bacteria are important subjects to scientists studying different life forms. Uses diagrams to show the importance of how bacteria reproduce within a cell and how various substances at certain points of production leads genes to change being identified. Describes the 'copy' errors responsible for mutation, and the ways in which gene-reading among viruses takes place
