Cas9 nucleases can be programmed with single guide RNAs (sgRNAs) to mediate gene editing High CRISPR/Cas9mediated gene knockout efficiencies are essential for genetic screens and critically depend on the properties of the sgRNAs used The specificity of an sgRNA is defined by its targeting sequence Here, we discovered that two short sequence The seed segment of gRNA and PAM are two elements that determine Cpf1 specificity It seems that Cpf1 has a lower threshold for nonseed mismatches visavis Cas9 Seed region flanks at the initial part of the spacer and plays a notable role in the target specificity of CRISPR–Cpf1 system (FigGrna seed region Grna seed regionAn approach called CREATE enables multiplex genome engineering, protein engineering and mapping of mutations in bacterial and yeast cells Improvements in DNA synthesisDe Strasbourg à l'Est à NogentsurSeine à l'Ouest, la Région Grand Est s'étend sur 57 500 km² Elle compte 9 départements Ardennes, Aube
