Claim:
1. A method of tagging nucleic acid duplexes comprising the steps of: (a) providing a transposase and a transposon composition; (b) providing one or more nucleic acid duplexes immobilized on a support, wherein the one or more nucleic acid duplexes are DNA:RNA duplexes; and (c) contacting the transposase and transposon composition with the one or more nucleic acid duplexes under conditions wherein the one or more DNA:RNA duplexes and transposon composition undergo a transposition reaction to produce one or more tagged DNA:RNA duplexes, wherein the DNA:RNA duplexes are tagged on the 5′ end of the RNA strand, and wherein the transposon composition comprises a double stranded nucleic acid molecule comprising a transferred strand and a non-transferred strand.
