High-cost of oligonucleotides is one of the major problems to low-cost gene synthesis. Although DNA oligonucleotides from cleavable DNA microchips has been adopted for the low-cost gene synthesis, construction of DNA molecules larger than 1. kb has been largely hampered due to the difficulties of DNA assembly associated with the negligible quantity of chip oligonucleotides. Here we report a hierarchical method for the synthesis of large genes using oligonucleotides from programmable DNA microchips. Using this hierarchical method, we successfully synthesized 1056. bp Dpo4 and 2325. bp Pfu DNA polymerase genes as models. This hierarchical strategy can be further expanded for the syntheses of multiple large genes in a scalable manner.
