We have cloned and characterized three fragments of Balb/c mouse DNA which hybridize to mouse cell tRNAs. Fractionation of the tRNAs which hybridize to these clones reveals that two of the clones,
Mt-4A and
Mt-6A hybridize to only one or two tRNAs, while one clone,
Mt-4B, hybridizes to at least seven tRNAs. Two of the tRNAs were identified as
and
, and others have been identified as tRNAs which are selectively encapsidated into virions of rourine leukemia virus and avian reticuloendotheliosis virus. The DNA sequences of putative genes for
and
, plus flanking regions, were determined. A clone of Balb/c mouse DNA which selectively hybridized to 5S rRNA was also isolated and partially characterized.
