Gene structure representation and detailed alignment view. The figure shows the WebScipio gene structure representation of the Drosophila melanogaster Dscam gene with mutually exclusive spliced exons and a section of the alignment view including exon 5 and the first two identified alternative exon candidates. The colours in the gene structure figure are the same as the colours of the exon identifiers in the text alignment. The opacity of the colours of each alternative exon corresponds to the alignment score of the alternative exon to the original one. This score is shown in the detailed alignment view next to the exon identifier. For each exon the genomic sequence, its translation, and the translation of the original exon is shown. Identical residues are illustrated as dashes and mismatches as red highlighted crosses. The crosses are highlighted in light red for amino acids, which are chemically similar. Gaps are marked as green hyphens.
