Structure and proteins of rotavirus. A). The viral genome of 11 segments of double-stranded RNA is analyzed by polyacrylamide gel electrophoresis. Each gene codes for at least one protein as shown with at least one major function of the protein indicated. B). A cut-away of the viral structure as determined by image reconstruction after electron cryo-microscopy is shown with the proteins designated that make up each concentric protein layer.
