Structure of endogenous murine leukemia virus DNA in mouse genomes.


By using molecularly cloned ecotropic AKR murine leukemia virus (MuLV) DNA, a 400-base-pair ecotropic type-specific segment in the env region has been identified. This DNA segment and other defined viral subgenomic fragments have been used as 32P-labeled probes to identify and analyze the structure of integrated ecotropic viral DNA sequences in uninfected… (More)
