RAPID PRODUCTION OF DOUBLE-STRANDED TARGET DNA MOLECULES

摘要

It has been previously disclosed that DNA segments can be made in massivel parallel chemical synthesis operations on a common substrate followed by release of the segments from the substrate and assembly of the segments into target DNA molecules. Here it is taught that if the DNA primary constructs are sufficiently long and properly designed, that the copy numbers of the primary constructs can be multiplied as needed by a PCR process using as a template regions at the ends of the primary constructs. The end regions, called flanking regions, can also be designed so that they may be cleaved easily from the amplification products. The target DNA can then be assembled from the cleaved fragments. Hundreds of thousands of oligonucleotides can be synthesized and assembled into many different individual genes by this process in a relatively quick and efficient process.
