Let me help you with virology.
DNA viruses all replicate in the nucleus because they require host polymerases. Exceptions include Poxviridae (Like smallpox are the largest viruses that have their own enzymes) and Hepadnaviridae (Hep B) that actually has its own RT.
RNA viruses all replicate in the cytoplasm as no host enzyme can replicate RNA anyway from an RNA template except for orthomyxoviridae (Influenza) and obviously retroviruses. +RNA viruses are quickly translated and therefore the naked RNA is infectious.
