Abstract
Total nucleic acids prepared from a number of murine retroviruses have been shown to contain virus-specific DNA in addition to genomic RNA. This virus-specific DNA has been shown to be at least partially double stranded and to be present within the virus core particle. The DNA isolated from the virus is greatly enriched in virus-specific DNA relative to that from virus infected cells.
