Patent Images
1. A composition comprising a plurality of isolated oligonucleotides at least some of which are nonidentical in sequence, length or both, wherein each of the oligonucleotides comprises:
- a) a defined sequence of at least 16 nucleotides, wherein at least a portion of the sequence is complementary to a target nucleic acid,b) at least one cleavage site, and optionallyc) at least two different subsequences separated by at least one of the cleavage site sequences, wherein each of the subsequences of each oligonucleotide binds to a different site in the target nucleic acid or each of the subsequences binds to a different target nucleic acid.

9. A method for preparing a plurality of primers, comprising:
-
a) selecting at least one target nucleic acid; b) identifying a sequence for each of a plurality of oligonucleotides, wherein each sequence comprises i) a defined sequence of at least 100 nucleotides wherein at least a portion of the sequence is complementary to a target nucleic acid, and ii) at least one cleavage site; c) synthesizing each of the oligonucleotides at a different address on the substrate; and d) cleaving each of the oligonucleotides from the array. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
