A facile method for the construction of synthetic genes (original) (raw)

A simple protocol for rapid assembly of chemically synthesized deoxyoligonucleotides into double stranded DNA is described. Several parameters of a ligation-free method were investigated to allow efficient assembly of a large number of oligonucleotides into double stranded DNA by polymerase chain reaction. Synthesis of a 701 bp DNA was carried out in a single reaction by assembling 28 oligonucleotides designed with partial overlaps at complementary ends. An estimate of error rate was made by sequencing several independent clones of the synthesized DNA.
