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. Anastassiou et al. Genome
