Size distribution of the C. elegans sRNA sequences. a, b Bar charts presenting number of sequences for each sRNA sequence length from 15 to 30 nt. The sequences are from one sample from embryo stage (a) or L4 larval stage (b). c, d Bar graphs presenting percentage of sRNAs for each sequence length from 15 to 30 nt from total number of sequences. c Average of three biological replicates at embryo stage. d Average of three biological replicates at L4 larval stage. Standard deviation is also presented. Black bars represent sequences that align to the genome, dark gray bars are sequences that did not align to miRNAs from sequences presented in the black bars, light gray bars represent sequences from the dark gray bars that also did not align to 21 U sRNAs
