This indicates that there are differences between viruses and cells. In the following table are listed several features of either viruses or cells or both. New individuals arise by binary fission of the parent. NO Proteins are translated from messenger RNAs. New individuals assemble by spontaneous association of subunit structures.
Subunit vaccines consist of one viral protein that can be given to stimulate an immune response.
You wish to produce a subunit vaccine for a positive strand RNA virus in the Baltimore classification scheme that will stimulate the production of neutralizing antibodies in the person receiving it. The capsomer protein is on the outside of the virion and could be the attachment site for a neutralizing antibody. This protein is on the inside of the virion and could not interact with a neutralizing antibody. Positive strand RNA viruses do not have virion-associated polymerases. The RNA polymerase is made in the cell during infection.
