Every cell that is successfully transfected with all three DNA fragments will produce the necessary proteins to produce infective viruses.

Helper dependent viruses can also occur in nature without being "gutted". The term satellite virus has been given to a large group of viruses that all require the presence of another virus to replicate. Many of these are plant viruses, but animal viruses can be seen in the case of
