Figure 2.

A zoomed-in view of the human and non-human mRNA tracks in the chrX:151 572 101–151 572 240 region on the human March 2006 (Build 36, hg18) genome assembly. In both mRNA tracks, the mRNA coloring options are configured to show nonsynonymous codon differences between the mRNA alignments and the genomic feature at the top of the figure. Red indicates codons that differ from the human genomic sequence. The double horizontal lines in the ‘Non-Human mRNAs’ track highlight areas in which both the mRNA and the genome sequence have an insertion or stretch of non-matching sequence. Note the blue vertical line at the beginning of the bottom Rattus alignment, indicating an insertion at the beginning of the query sequence, also the orange vertical lines with partial peptide insertions in the Rattus alignments.
