miRNA activity is associated with miRNA abundance.

(A, B) Correlation between miRNA quantity and number of seeds with the number of predicted miRNA targets. y-Axis  =  log2(x), x-axis  =  log10(x). (C, D) Correlation between miRNA quantity and number of seeds with the number of validated miRNA targets. For these calculations, we used miRNAs with at least one validated target gene. y-Axis  =  log2(x), x-axis  =  log10(x).
