1. A method of sorting a mixture of nucleic acid strands comprising the steps of:
- a) providing a solution containing a mixture of nucleic acid strands in single-stranded form andb) contacting said solution to a first binary oligonucleotide array of predetermined areas on a surface of a solid support, each area having therein, covalently linked to said surface, copies of a binary oligonucleotide, said binary oligonucleotide consisting of a constant nucleotide sequence adjacent to a variable nucleotide sequence, wherein the constant nucleotide sequence is the same for all oligonucleotides in the array, wherein said step of contacting is carried out under conditions promoting perfect hybridization of said strands to said binary oligonucleotides.

Abstract
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.

58. A method for sorting partials by their variable termini on a binary oligonucleotide array, which partials have been prepared by random chemical or enzymatic degration of one or more nucleic acid strands, said binary array comprising an array of predetermined areas on a surface of a solid support, each area having therein copies of a binary oligonucleotide of a predetermined sequence, said binary oligonucleotide consisting of a constant nucleotide sequence adjacent to a variable nucleotide sequence, said variable nucleotide sequence being at the free end of the binary oligonucleotides, said binary oligonucleotide also having a complementary masking oligonucleotide hybridized to all or a part of the constant nucleotide sequence, including the portion of the constant nucleotide sequence adjacent the variable nucleotide sequence, comprising the steps of:
-
(a) hybridizing the partials to the array by their termini under conditions that promote the formation of perfect hybrids; and (b) ligating the termini of the partials to the masking oligonucleotide.
