X-RAY diffraction data and chemical evidence suggest that the protein content of tobacco mosaic virus rods is built up of small sub-units1. A model has been proposed2 in the form of a helix of ...

STRAINS of tobacco mosaic virus differ markedly in sensitivity to inactivation with ultra-violet light1. It is of interest to determine the basis for this difference in terms of the chemical ...
