Expanding annotation in alignments. Human (chr7:154600000–155050000) and mouse (chr5:25950131–27951930) 420-kb alignment for the Sonic Hedgehog/Engrailed region. Genomic sequences and RefSeq (A) or mRNA (B) annotation files were uploaded from the UCSC genome database. Using mRNA data, the RefSeq annotation was dynamically edited to include the most complete set of exons (C).
