The length and counts characteristics of the sequencing results.

<p>(A) The length distribution of sequenced small RNAs. The red-pinkish colors indicate prenatal samples and blue colors indicate postnatal samples. (B) Plot of the unique miRNAs (starting from the miRNA with the highest counts, x-axis) versus their accumulative % in total counts of the mappable sequences. The dashed horizontal line at 54.3% represents the level of the total 771 unique miRNAs and the % of individual miRNA is marked by the gray line.</p>
