UCSC genome browser screenshots illustrating alignment of reads to two tRNA genes. Shown are the Illumina sequencing reads (red), and the tRNA genes (blue) as annotated in the tRNA genes track ”Transfer RNA genes identified with tRNAscan-SE“. (A) The alignment (number of reads, y-axis) shows that all the sequencing reads align to the 5′ end of chr1.tRNA704-GlyGCC gene. (B) The majority of the sequencing reads align to the 5′ end of chr11.tRNA945-ArgCCG gene, whereas only a very small number of sequencing reads aligns to the 3′ end.
