Yоu аre studying а new оperоn in а bacterial species. The rib operon codes for genes needed for the use of ribitol as a carbon and energy source. The rib operon is subject to both positive and negative transcriptional regulation, at the level of initiation. An activator protein called RibG binds the rib operator and promotes transcription when ribitol is available. When ribitol is not present, the RibG protein no longer does this. So, when ribitol is present you would expect that transcription would be [blank1] and when ribitol is absent you would expect that transcription would be [blank2].
