E)repression of transcription.

Question

Binding of a positive regulatory protein to a promoter element results in activation of transcription, as it helps recruit RNA polymerase and other transcription factors, leading to gene expression. Activation of replication or translation is not directly related to promoter elements, while repression of replication or transcription would occur with negative regulatory proteins binding to the promoter element.
