“…A newer innovation involves transposonmediated fragmentation and adaptor ligation, processes originally designed for DNA sequencing that can be adapted for RNA-Seq library preparation (Syed 2010;Gertz et al 2012). Unlike previous RNA-Seq preparation methods, in which polyadenylated RNA ( polyA RNA) was selected and fragmented, then converted to double-stranded cDNA (ds cDNA), the new method involves a polyA RNA selection step during first-strand cDNA synthesis followed by transposon-based fragmentation of ds cDNA.…”
