Fig 6. Global modification profile of all samples showing high levels or adenylation and uridylation at the 3′ end of the miRNA.

The x-axis corresponds to the index positions across a miRNA molecule. They y-axis corresponds to the raw counts of the identified modification patterns. The start of a miRNA on the x-axis is at index ‘0’ (5′ end) while its end is at index ‘22’ (3′ end).
