Screen shot of the UCSC Genome Browser (http://genome.ucsc.edu) conservation tracks of the mfl 3' genomic region. The region examined, spanning exons 6–12 (black boxes), is shown at the top. The conservation track has two parts: a plot of conservation scores, and beneath it, a display showing where each of the other genomes aligns to the reference sequence (darker shading indicates higher BLASTZ scores; white indicates no alignment). Peaks of cross-species conservation are observed at each 3 'UTR intron, but only sequences of the DmSnR60 isoforms are highly conserved among all the annotated genomes of the Drosophila species.
