In order to confirm the significance of this region in the context of viral replication, we constructed several of these LS mutations ( -201 to - 184 , -183 to -166 , -165 to -148 , and -148 to -130 ) in proviruses and prepared viral stocks by cocultivation of transfected RD cells with CEMx174 cells .
 ( DNA: -183 to -166, None) , ( DNA: -201 to - 184, None) , ( DNA: -148 to -130, None) , ( cell line: CEMx174 cells, None) , ( cell line: transfected RD cells, None) , ( DNA: -165 to -148, None)
