by subjecting the heterologous drc to sonication and alkaline cscl gradient centrifugation , it was established that the drc consisted of three components : ( 1 ) recipient dna in which breakdown products of donor dna were incorporated through dna synthesis , ( 2 ) recipient dna in which donor dna was covalently integrated and ( 3 ) recipient dna in which the donor moiety was not covalently integrated .
