these studies demonstrate that ( i ) the large terminal repeat sequence of mc29 is very similar to that of rous sarcoma virus , ( ii ) the viral genome has suffered extensive deletions in the gag , pol , and env genes , ( iii ) the gag region can code for p19 , p10 , and part of p27 , ( iv ) the recombination between viral and cellular sequences occurred in the coding region of p27 such that the open reading frame extends for an additional stretch of 1,266 base pairs , resulting in a gag-myc hybrid protein , ( v ) the open reading frame terminated within the v-myc region 300 bases upstream of v-myc-helper viral junction , and ( vi ) the v-myc helper-viral junction at the 3 ' end occurred in the middle of env gene , rendering it defective .
