BIOSYNTHESIS OF DNA VIRUSES In general, DNA virus nucleic acid enters the nucleus of the host cell ad is replicated there, using  viral enzymes. The capsid and other proteins are synthesized in the cytoplasm, using host cell  ribosomes and enzymes. These proteins then migrate into the nucleus and are joined with the  newly synthesized DNA to form virions, which are then released from the host cell. Poxviruses  are an exception to this; all their components are synthesized in the cytoplasm.    BIOSYNTHESIS OF RNA VIRUSES Since these viruses have RNA as their only nucleic acid, their mechanisms of mRNA formation  must differ from those used to make mRNA using DNA as the template. RNA viruses multiply in  the host cell’s cytoplasm. The major differences among the multiplication processes of these  viruses are the ways mRNA and copies of the viral RNA are produced.
