Abstract
The present invention relate to methods and compositions for simultaneously analyzing multiple different polynucleotides of a polynucleotide composition comprising multiple diverse polynucleotide sequences. The subject methods and compositions may also be applied to analyze or identify single polynucleotides; however, the subject methods and compositions are particularly useful for analyzing large diverse populations of polynucleotides, e.g., cDNA libraries. Most embodiments of the invention involve hybridizing terminus probes (of known base sequence) to adapter-modified restriction fragment generated from polynucleotide for analysis, and subsequently joining the terminus probes and internal fragment probes to each other. The terminus probe hybridizes to bases of restriction endonuclease recognition site present at the terminus of a restriction fragment generated from the polynucleotide for analysis. The terminus probes and internal fragment probes may be marked so as to facilitate the simultaneous testing of multiple polynucleotides for the presence of many possible nucleotide base sequences. The identity or expression of a particular polynucleotide of interest may be ascertained …
