Bias with respect to A+/T+ segment boundary – estimates for combined effect of transcription. The brown line shows the AT-bias where there is no transcription. The green line shows the AT-bias where there is transcription in the direction from the A+/T+ boundary to the T+/A+ boundary. The red line shows the bias where there is transcription in the opposite direction. All lines show moving averages over 100 bases.
