Identifying the targetome of a microRNA is key for understanding its functions. Cross-linking and immunoprecipitation (CLIP) methods capture native miRNA-mRNA interactions in cells. Some of these methods yield small amounts of chimeric miRNA-mRNA sequences via ligation of 5'-phosphorylated RNAs produced
