Detailed explanation-1: -All DNA viruses replicate within the nucleus except poxviruses, asfarviruses, and phycodnaviruses. Few RNA viruses, including bornaviruses, orthomyxoviruses, and retroviruses, replicate in the nucleus.
Detailed explanation-2: -All DNA viruses except the family Poxviridae carry out their replication in the nucleus, and therefore would not be capable of completing their life cycles in enucleated cells. Indeed, poxviruses are DNA viruses that replicate entirely in host cell cytoplasm.
Detailed explanation-3: -DNA viruses undertake their replication within the cell nucleus, and therefore they must first deliver their genome into the nucleus of their host cells. Thus, trafficking across the nuclear envelope is at the basis of DNA virus infections.
