Fig. 1From: microRNAs associated with early neural crest development in Xenopus laevisSize class distribution of small RNAs shows a bimodal distribution with peaks at 23Â nt (miRNAs) and 29Â nt (piRNAs and other sRNAs). In neural tissue 16.1% of reads are miRNA. In NC 15% of reads are miRNA. In ectoderm 18% of reads are miRNA. In blastula 5.6% of reads are miRNABack to article page
