Nuclear exit of viral genome
All nuclear replicating viruses must get their progeny out of the nucleus. This process requires dedicated viral proteins, indeed it is unnatural for a cell to let DNA or un-spliced RNA material escape from the nucleus.
Three major ways allows nuclear virus exit from this organelle: Nuclear pore export: export of genetic material with a shuttle protein Nuclear egress: budding, and fusion through the nuclear membranes to reach cytoplasm Nuclear envelope breakdown
