A method of sorting mixtures of nucleic acid strands comprising hybridizing the strands to an array of immobilized oligonucleotides, each of which includes a constant segment adjacent to a variable segment. The constant segment of the immobilized oligonucleotides can be made complementary to the ends of strands obtained by digesting a double-stranded nucleic acid with a restriction enzyme and restoring the restriction sites, thereby permitting the sorting of strands according to their variable sequences adjacent to their constant terminal restored restriction sites. |
