## Figure 5.
Strand bias with respect to A+/T+ segment boundaries – comparison with no recorded
transcription. The orange line shows the AT-bias for the entire sample. The red line shows the
AT-bias for the boundaries where there is no recorded transcription from coding genes
for 50 kb either side of the boundary – this line is based on 4997 segment boundaries.
The blue line shows the AT-bias for the boundaries where there is some recorded transcription
from coding genes within the range plotted – this line is based on 6753 segment boundaries.
The thickness of the red and blue lines show 95% confidence limits. All lines show
moving averages over 100 bases. There is a statistically significant difference between
the red and blue lines: at position 5000 bases downstream of the boundary a two-tailed
z-test gives p-value < 10^{-50}, n1 = 4997, n2 = 6753, z = -16.
