摘要:
Artificial transcription terminators and their use are provided herein. In one aspect, a non-naturally occurring nucleic acid sequence can comprise a Y-X-Z stem-loop, wherein: Y is a nucleotide sequence of 10 to 30 nucleotides in length; X is a nucleotide sequence of 3 to 12 nucleotides in length, each nucleotide therein not base pairing with any other nucleotide within X; and Z is a nucleotide sequence of 10 to 50 nucleotides in length and having at least 70% complementarity to Y.
摘要:
Methods and apparatus relate to the synthesis of polynucleotides having a predefined sequence on a support. Assembly methods include primer extension to generate overlapping construction oligonucleotides and assembly of the polynucleotides of interest onto an anchor support-bound oligonucleotides. Methods and apparatus for selection of polynucleotides having the predefined sequence and/or length are disclosed.
摘要:
Methods and compositions relate to the assembly of high fidelity nucleic acids. Specifically, nucleic acid molecules having a desired predetermined sequence can be assembled after failure to assemble in conventional assembly. Aspects of the disclosure relate to methods of assembling a target nucleic acid molecule having a desired or predetermined sequence.
摘要:
Methods for designing and producing non-random libraries of nucleic acids are presented. In particular, synthesis of nonrandom libraries by multiplexed polynucleotide synthesis is utilized. Each library member may encode a promoter, ribosomal binding site and polypeptide.
摘要:
Aspects of the disclosure relate to compositions and methods for site-directed DNA nicking and/or cleaving, and use thereof in, for example, polynucleotide assembly.
摘要:
There is disclosed a process for in vitro synthesis and assembly of long, gene-length polynucleotides based upon assembly of multiple shorter oligonucleotides synthesized in situ on a microarray platform. Specifically, there is disclosed a process for in situ synthesis of oligonucleotide fragments on a solid phase microarray platform and subsequent, "on device" assembly of larger polynucleotides composed of a plurality of shorter oligonucleotide fragments.
摘要:
Aspects of the invention relate to methods, compositions for designing and producing a target nucleic acid. In particular, aspects of the invention relate to the multiplex synthesis of target polynucleotides.
