Figure: $R_{frequency} = \log_2{812} = 9.7$ cI/cro operator information content, determined as for Figure 1.

  

Figure 11: T7 promoter information content, determined as for Figure 1.

The center of the symmetry element is marked by a bar and the points of symmetry by dots. The start of transcription at base zero is shown by an arrow.

  

Figure 12: T7 promoter symmetry element.

The sequences of the 17 T7 polymerase binding sites are shown. Position zero is presumed to be the start point for transcription (Dunn and Studier, 1983). The position numbers are written vertically. The positions found to be part of the symmetry (Table 2) are shown as capital letters printed in bold face. The GAG's that may be shifted to the left by one base are indicated by an underline.

  

Figure 13: T7 symmetry element information content, determined as for Figure 1.

The information content outside the 12 positions of the symmetry element is from the asymmetric promoter sequences.
