摘要:
The invention provides methods and compositions relating to cells having altered functions, and the nucleic acids that impart those functions. Altered cellular function arises from in vivo directed recombination of genetic elements to yield a recombined nucleic acid. These methods and compositions may utilize altered host cells having altered recombination enzyme profiles and/or altered recombination sites. The invention involves in some aspects methods for assembling nucleic acid molecules, such as genomic DNA. Aspects of the invention also provide kits, compositions, devices, and systems for generating novel recombined nucleic acids and cells having altered cell function.

摘要:
A method for sequencing a nucleic acid polymer by (1) providing two separate, adjacent pools of a medium and an interface between the two pools, the interface having a channel so dimensioned as to allow sequential monomer-by-monomer passage from one pool to the other pool of only one nucleic acid polymer at a time; (2) placing the nucleic acid polymer to be sequenced in one of the two pools; and (3) taking measurements as each of the nucleotide monomers of the nucleic acid polymer passes through the channel so as to sequence the nucleic acid polymer.

摘要:
The present invention provides recombination based methods for assembling nucleic acids. In certain aspects the present invention provides hierarchical assembly methods for producing genome sized polynucleotide constructs. The methods may be used for assembling large polynucleotide constructs, for synthesizing synthetic genomes, or for introducing a plurality of nucleotide changes throughout the genome of an organism. In another aspect, the invention provides cells having increased genomic stability. For example, cells comprising alterations in at least a substantial portion of the transposons in the genome are provided.
