The ratio of physical virus particles to infectious particl

______ The ratio of physical virus particles to infectious particles can be much greater than 1. ______ Capsids play exactly the same roles in plant viruses as they do in animal viruses. _____ Scaffolding proteins are structural proteins that are part of the actual virion.

Solution

True. The ration of physical virus partilcles to infectious particles can be much greater than 1. A high particle-to-pfu ratio can be due to presence of noninfectious particles
