The EBNA transcription was initiated from one of three EBNA promoters , Qp : by contrast, both Cp and Wp were silent, thus resulting in the lack of EBNA2 mRNA .
 ( RNA: EBNA2 mRNA, None) , ( DNA: Qp, None) , ( DNA: EBNA promoters, None) , ( DNA: Wp, None) , ( protein: EBNA, None) , ( DNA: Cp, None) , ( protein: EBNA, None)
