Figure 2From: Identification and characterization of novel amphioxus microRNAs by Solexa sequencingCharacterization of amphioxus miRNAs. (a, b) Comparison of the number (a) and absolute sequencing frequency (b) of conserved miRNAs with those of amphioxus-specific miRNAs. (c) The composition of amphioxus miRNAs of various lengths (in nucleotides (nt)). (d) The size distribution of small amphioxus RNAs and miRNAs of various lengths sequenced by Solexa.Back to article page
