Targeted Comparative Sequencing Illuminates Vertebrate Evolution
Ricki Lewis | Dec 8, 2002 | 6 min read
Image: Courtesy of Elliott Marguiles  PIPS ON PARADE: Researchers used a MultiPipMaker to show the alignments, expressed as percent identity plots, between a human reference sequence and several other species. This is a 20 kb region surrounding exon 2 of the MET gene. Gap-free alignable segments are represented as horizontal lines along the human reference sequence; the line's height represents the identity of that alignment. Aristotle envisioned humanity as the pinnacle of a "Great Chai
