If the genome of a positive-strand RNA virus, which has been purified away from all of the virion proteins, was injected into the cytoplasm of an appropriate host cell, what would happen first?

Question

Quizplus · Accepted Answer

Positive-strand RNA viruses have genomes that can directly serve as mRNA. Therefore, upon entering the cytoplasm of a host cell, the viral RNA can immediately be recognized and translated by the host's ribosomes to produce viral proteins. This is the first step in the replication cycle of such viruses when only the RNA genome is introduced into the cell.
