What would happen if an enhancer sequence were mutated so that its binding partner was always bound and recruiting the RNA polymerase complex?
A)No transcription would occur as the site is now blocked to other proteins.
B)Transcription wouldn't change.
C)No transcription would occur because the mediator complex could not form.
D)Transcription would occur continuously.

If the enhancer sequence were mutated so that its binding partner was always bound and recruiting the RNA polymerase complex, transcription would occur continuously. The enhancer sequence, when bound by its partner, enhances the transcription process by recruiting the RNA polymerase complex to the promoter region. If the enhancer sequence is always bound, the recruitment of the RNA polymerase complex will continue uninterrupted, leading to continuous transcription.
