Fig. 2From: Elimination of PCR duplicates in RNA-seq and small RNA-seq using unique molecular identifiersUMI incorporation into small RNA-seq. a Overall workflow. The method uses a 3′ adapter composed of DNA, except for a single, 5′ ribonucleotide (rA); the 5′ adapter is entirely RNA. A standard index barcode allows multiplexing. b Schematic of a read produced from small RNA-seq with UMIsBack to article page
