14 results about "Proofreading" patented technology

The term proofreading is used in genetics to refer to the error-correcting processes, first proposed by John Hopfield and Jacques Ninio, involved in DNA replication, immune system specificity, enzyme-substrate recognition among many other processes that require enhanced specificity. The proofreading mechanisms of Hopfield and Ninio are non-equilibrium active processes that consume ATP to enhance specificity of various biochemical reactions.

Translation calibration method based on big data

The invention relates to the technical field of translation, and discloses a translation calibration method based on big data, which can accurately identify semantic deviation in a multi-meaning scene, for example, accurately judge that'cell 'should be translated into'cell' instead of'house 'in a biological text. The system can detect the language field mismatching problem of spoken expression in the official file, and provides term correction suggestions conforming to industry standards. Aiming at technical terms with multiple meanings in legal clauses, the calibration process can be combined with context window analysis to select an optimal translation scheme, the omission ratio of manual review is remarkably reduced, continuous optimization and cross-language knowledge sharing of a translation calibration model are realized, and the accuracy of translation calibration is improved. The problems that a traditional system is lagged in updating and low-resource language performance is insufficient are solved.

Fusion proteins comprising Cas proteins and bacterial toxins and uses thereof

Regarding a fusion protein comprising a Cas protein and a bacterial toxin and its use, the fusion protein, its polypeptide, and a CRISPR-Cas system comprising them according to one embodiment enable effective base proofreading. Furthermore, the polypeptide is small in size, making it easy to deliver via a vector. This significantly increases indel efficiency when indels are induced, and the size of the nucleotide at which indels are formed also increases, making it effective for gene knockout.

Highly efficient and simple SSPER and rrPCR approaches for the accurate site-directed mutagenesis of large plasmids

Presented arc two new methods, single primer extension reaction (SSPER) and reduce recycle PCR (rrPCR). These methods have a step that easily removes the oligonucleotide primer(s) after the first reaction, thus, allowing for the addition of a second reaction in chronological sequence to generate and isolate the appropriate DNA product with the site-directed mutation(s). A high efficiency of the methods is demonstrated by generating all ten site-directed mutations and six paired combinations of these mutations on four plasmid DNA templates ranging from 10 to 12 kb and 57 to 59% GC-content at a rate of 50-100%. The methods are i) highly accurate allowing for screening of plasmids by DNA sequencing, ii) streamlined to generate the mutations within a single day, iii) cost-effective in requiring only two primers and two enzymes (Dpnl and a proofreading DNA polymerase), iv) straightforward in primer design, and v) applicable for both large and small plasmids.
