These results support a model for viral promoter switching during the initial stages of infection in which Wp activity leads to the expression of EBNA 2 , followed by activation of Cp through the EBNA 2 -dependent enhancer .
 DNA: Cp; protein: EBNA 2; DNA: EBNA 2 -dependent enhancer; DNA: Wp; DNA: viral promoter; protein: EBNA 2
