11. A method of preparing a polynucleotide having a target sequence from a plurality of oligonucleotides, said method comprising:
-
(a) blocking the 3′
end of each of said oligonucleotides, except for the oligonucleotide comprising the 5′
terminus of said polynucleotide, with a blocking group to form a plurality of blocked oligonucleotides;
(b) coupling the 5′
end of each of said blocked oligonucleotides with the 3′
end of a further oligonucleotide of said plurality of oligonucleotides to form a plurality of coupled oligonucleotides, wherein said further oligonucleotide comprises a portion of said polynucleotide immediately 5′
to the sequence of said blocked oligonucleotide, wherein each of said coupled oligonucleotides shares at least one oligonucleotide with another coupled oligonucleotide; and
(c) assembling said polynucleotide by extension of said coupled oligonucleotides. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

- 23. A method of coupling a first oligonucleotide with a further oligonucleotide, wherein said first oligonucleotide is attached to solid support, comprising contacting said first oligonucleotide with ligase and cosubstrate to form activated oligonucleotide, washing said activated oligonucleotide to form washed oligonucleotide, and contacting said washed oligonucleotide with said further oligonucleotide and ligase.
