摘要:
Disclosed are methods of manufacturing synthetic DNAs, that is, DNAs made at least in significant part by chemical synthesis of nucleic acid polymers. Also provided are methods for assembling plural DNAs in the same pool by multiplexed assembly of synthetic oligonucleotides. In exemplary embodiments, the methods involve pre-amplification of one or more oligonucleotides using “universal” primers, reduction of the error rate in oligonucleotide and/or nucleic acid products, and sequence optimization and oligonucleotides design. Also provided are low-purity arrays of nucleic acids and methods for assembling nucleic acids using oligonucleotides obtained from low-purity arrays.

Methods and compositions are provided for manipulating the genome of host cell to produce at least one exogenous gene product. Also provided are methods and composition for producing a programmable cell comprising a plurality of exogenous genes, wherein each exogenous gene is under the control of a disrupted regulatory sequence and wherein the disrupted regulatory sequences are restored by in vivo recombination. Preferably, the gene of interest is under the control of a genetically altered promoter which sequence recombination effects the expression of the exogenous gene(s).

Disclosed are methods for synthesizing and/or assembling at least one polynucleotide product having a predefined sequence from a plurality of different oligonucleotides. In exemplary embodiments, the methods involve synthesis and/or amplification of different oligonucleotides immobilized on a solid support, release of synthesized/amplified oligonucleotides in solution to form droplets, recognition and removal of error-containing oligonucleotides, moving or combining two droplets to allow hybridization and/or ligation between two different oligonucleotides, and further chain extension reaction following hybridization and/or ligation to hierarchically generate desired length of polynucleotide products.
