Figure 4

Dot plots illustrating the binding sites upstream of each alternative exon 6 in Drosophila melanogaster. The horizontal axis shows the distance in nucleotides from the exon to be chosen. The vertical axis indicates the nucleotides of the anchor sequence. The dot plots were created using the '8 out of 11' method and were further processed to filter out any dots that are not part of a continuous line of length at least 4. Line lengths should be seen as approximate indicators and not as precise measures of binding strength.
