The mRNA track shows alignments of chimpanzee and human mRNAs in GenBank and the genome.
This track follows the display conventions for PSL alignment tracks. In dense display mode, the items that are more darkly shaded indicate matches of better quality.
The description page for this track has a filter that can be used to change the display mode, alter the color, and include/exclude a subset of items within the track. This may be helpful when many items are shown in the track display, especially when only some are relevant to the current task.
To use the filter:
This track may also be configured to display codon coloring, a feature that allows the user to quickly validate and compare mRNA. For more information about this option, click here.
GenBank chimpanzee and human mRNAs were aligned against the genome using the blat program. When a single mRNA aligned in multiple places, the alignment having the highest base identity was found. Only alignments having a base identity level within 0.5% of the best and at least 96% base identity with the genomic sequence were kept.
The mRNA track was produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
