Characterization of sequenced data from three miRNA libraries of Ciona savignyi larvae. a Size distribution of sequenced small RNAs. b The classification and abundance of small RNA sequencing reads. Known miRNA, miRNAs that align to miRNAs in miRBase; novel miRNA, miRNAs that do not match any known miRNA/RNA sequence; rRNA, ribosomal RNA; tRNA, transfer RNA; snRNA, small nuclear RNA; snoRNA, small nucleolar RNA; repeat, repeat associate RNA; exon:+, exon in the DNA sense strand; exon:-, exon in the DNA antisense strand; intron:+, intron in the DNA sense strand; intron:-, intron in the DNA antisense strand; other, sequences do not match above classifications. c The frequency of miRNA nucleotide bases (A/U/C/G) at each position. Purple represents U, blue represents G, green represents C, and red represents A
