Different modes of the mix-and-matching mechanism: The promoter elements participating in mix-and-matching are divided to dsDNA (shaded in red) and ssDNA-interacting (shaded in green); In the upper part of the figure the complementation between the strengths of the dsDNA-interacting elements for achieving sufficient level of dsDNA-binding affinity is shown; in the lower part of the figure the complementation between the strengths of the dsDNA and ssDNA-interacting elements for achieving sufficient level of transcription activity is shown; the strength of the promoter element which is indicated by the size of the corresponding font and arrow
