. Structure of the ribonucleic acid bacteriophage R17. J. Bacteriol.

1779–1786. 1966.—The morphology of bacteriophage R17 was studied by electron microscopy of negatively stained virions. The hexagonal shape, the presence of a maximum of 10 units at the periphery, and especially the observation of central fivefold points of symmetry with neighboring five and six coordinated units indicated icosahedral symmetry with 32 morphological units. Although the exact shape of the polyhedron could not be specified, the number of morphological units agreed with the chemically estimated number of structural units.
