1. A method of nucleic acid processing comprising:
providing an adapted nucleic acid fragment comprising a nucleic acid fragment linked at its 3′-end to a 3′-adapter molecule by a triazole linkage comprising a 1,2,3-triazole group, wherein the 3′-adapter molecule comprises RNA, DNA, a nucleic acid analogue or combinations thereof;
annealing a primer to the adapted nucleic acid fragment, wherein the primer anneals to a region of the 3′-adapter molecule; and
processing the adapted nucleic acid fragment by transcribing at least a portion of the adapted nucleic acid fragment with reverse transcriptase, wherein said portion of the adapted nucleic acid fragment transcribed with reverse transcriptase comprises said triazole linkage.
