Distribution of endogenous murine leukemia virus DNA sequences among mouse chromosomes.
We used mouse-Chinese hamster somatic cell hybrids which lose mouse chromosomes to examine the distribution of murine leukemia virus DNA sequences in the genome of A/HeJ mice. We analyzed total cellular DNA from various hybrid clones for the presence of viral sequences by molecular hybridization and used the Southern blot hybridization procedure to identify viral DNA in cellular restriction endonuclease fragments. Our results show that murine leukemia virus DNA sequences are distributed among many mouse chromosomes in this strain. Chromosome 4 was shown to contain murine leukemia virus DNA sequences.
