Figure 1.

An example showing how a micro-exon improves a cDNA alignment. (a) Alignment showing the boundaries of the fourth and fifth exons from the sim4 alignment of cDNA Ceres:20761 to chromosome 4. (b) The improvement resulting from insertion of a micro-exon; all three exons now align with 100% identity to the cDNA sequence. Intron positions are shown by '>' in the alignment.
