An amplified endogenous retroviral sequence on the murine Y chromosome related to murine leukemia viruses and viruslike 30S sequences.

A highly repeated sequence on the murine Y chromosome was cloned and characterized. The DNA sequence of the viral long terminal repeats (LTRs) showed that the 59 and 39 LTRs were approximately 90% homologous. The LTRs are generally unrelated to any previously reported viral LTR but are somewhat similar to the viruslike 30S sequences. Images
