1. A method of amplifying genomic fragments, comprising the steps:
- (a) digesting genomic DNA into genomic fragments, wherein said digesting results in genomic fragment overhangs;
(b) contacting said genomic fragments with one or more adapters, wherein said adapters are complementary to at least two of said overhangs;
(c) ligating said adapters to said genomic fragment overhangs to form closed adapter-genomic fragment circles;
(d) separating said adapter-genomic fragment circles from linear fragments; and
(e) amplifying said adapter-genomic fragment circles.

18. Two sets of universal building blocks comprising:
a first set of single-stranded oligonucleotides having a first end and a second end, said first end having a sticky-end overhang and said second end having sequence of 8-20 bases; and
a second set of single-stranded oligonucleotides having a first end and a second end, said first end having a sticky-end overhang and said second end having a sequence of 8-20 bases, wherein said first ends of said first and second sets are different, and said second end of said first set are complementary to said second end of said second set, generating all possible combinations of adapter sequences.- View Dependent Claims (19, 20, 21)
