Formula omitted] association of unique species of cellular 4S RNA with 35S RNA of RNA tumor viruses

Abstract

Unique 4S RNA species from AKR mouse embryo cells hybridize with AKR murine leukemia virus and avian myeloblastosis virus 35S RNAs in vitro . Analyses by reversed-phase column chromatography indicate that the major 4S species that hybridize with the two viral RNAs are probably the same. A 4S RNA species with similar chromatographic properties is a major component of the AKR viral 4S RNA which associates with the viral 70S RNA in vivo .
