by studying the segregation of mmtv-specific ecori , bamhi , and psti fragments , the organization of these fragments into mmtv proviral loci was determined and it was shown that ( 1 ) many homologous proviral loci are present in these three mouse strains , ( 2 ) these mmtv proviruses differ in their pattern of internal restriction sites , and ( 3 ) the mmtv loci are distributed on multiple chromosomes including 1 and 7 .
