This track displays translated blat alignments of mRNA for all Drosophila species from Genbank.
The strand information (+/-) for this track is in two parts. The first + indicates the orientation of the query sequence whose translated protein produced the match (here always 5' to 3', hence +). The second + or - indicates the orientation of the matching translated genomic sequence (+ or -).
mRNAs for all Drosophila species are aligned against the genome using the blat program. blat is run in translated mode. When a single mRNA aligns in multiple places, only the best alignments which also have at least 25% sequence identity are kept.
The all-Drosphila mRNA track is produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
