1. A method for covalently linking two nucleic acid segments, the method comprising:
- (a) incubating the two nucleic acid segments with an exonuclease under conditions that allow for digestion of termini of the two nucleic acid segments to form complementary single-stranded regions on each nucleic acid segment and hybridization of the complementary single-stranded regions, wherein each of the two nucleic acid segments comprises an exonuclease resistant region within 30 nucleotides of the end of the complementary terminus, and(b) covalently connecting at least one strand of the hybridized termini formed in (a) resulting in the linkage of the two nucleic acid segments.

15. A method for assembling a nucleic acid molecule, the method comprising:
-
(a) incubating a first nucleic acid segment with an exonuclease under conditions that allow for partial digestion of at least one terminus of the first nucleic acid segment to form a single-stranded region, wherein the first nucleic acid segment contains an exonuclease resistant region within 30 nucleotides of the at least one terminus, (b) preparing a reaction mixture containing the digested first nucleic acid segment formed in (a) with an undigested second nucleic acid segment under conditions that allow for the hybridization of termini with sequence complementarity, and (c) covalently connecting at least one strand of the hybridized termini formed in (b). - View Dependent Claims (16, 17, 18, 19, 20)

21. A method for assembling a nucleic acid molecule, the method comprising:
-
(a) incubating two or more nucleic acid segments with an exonuclease under conditions that allow for partial digestion of at least one terminus of each of the two or more nucleic acid segments to generate single-stranded termini, wherein at least two of the two or more nucleic acid segments contain an exonuclease resistant region within 30 nucleotides of at least one of their termini, (b) preparing a reaction mixture containing the digested nucleic acid segments prepared in (a) with one or more undigested nucleic acid segment under conditions that allow for the hybridization of termini with sequence complementarity, wherein at least one of the one or more undigested nucleic acid segment has region of sequence complementarity with at least one single-stranded terminus formed in (a), and (c) covalently connecting at least one strand of the hybridized termini formed in (b).
