Accepted Answer

The promoter is the site on DNA to which RNA polymerase binds before initiating transcription. The terminator is the site that signals the end of transcription, the operator is a site at which a repressor protein can bind to regulate gene expression, the enhancer is a DNA sequence that can increase transcription levels, and the silencer is a DNA sequence that can decrease transcription levels.
