1. A method of analyzing rare nucleic acid species comprising:
- (a) providing a library of double-stranded nucleic acids;
(b) denaturing the library;
(c) renaturing the library under conditions sufficient to renature abundant nucleic acid species, wherein a portion of the library comprising less abundant nucleic acid species does not renature;
(d) contacting the library with a transposase that preferentially binds to double-stranded nucleic acids; and
(e) separating renatured abundant nucleic acid species from the less abundant nucleic acid species.

Abstract
Presented herein are methods and compositions for analyzing rare nucleic acid species. Some methods presented herein use DNA reassociation kinetics following thermal denaturation to define populations of nucleic acid sequences, e.g., highly abundant (e.g., cDNA from rRNA), moderately abundant, and less abundant or rare sequences (e.g., cDNA from mRNA).
