Can We Regulate Gene Editing Without Killing It?
... If there was really any hope that the new gene-editing techniques would be accepted as benign by anti-GMO activists, it has vanished. Second in a series of posts by Tabitha M. Powledge. Last week I wrote about how Chinese researchers used a gene editing method, the one called CRISPR, to silence thre ...

... The CRISPR/Cas9 system is a powerful tool for targeted gene editing, in which a single guide RNA (sgRNA) directs a Cas9 nuclease to a specific genomic locus. Cas9 cleaves the gene of interest and creates a double stranded break (DSB) in the DNA, which can be repaired by nonhomologous end joining ( ...

CRISPR
CRISPRs (clustered regularly interspaced short palindromic repeats) are segments of prokaryotic DNA containing short repetitions of base sequences. Each repetition is followed by short segments of ""spacer DNA"" from previous exposures to a bacterial virus or plasmid. It is pronounced ""crisper"".The CRISPR/Cas system is a prokaryotic immune system that confers resistance to foreign genetic elements such as plasmids and phages, and provides a form of acquired immunity. CRISPR spacers recognize and cut these exogenous genetic elements in a manner analogous to RNAi in eukaryotic organisms. CRISPRs are found in approximately 40% of sequenced bacteria genomes and 90% of sequenced archaea.The CRISPR/Cas system has been used for gene editing (adding, disrupting or changing the sequence of specific genes) and gene regulation in species throughout the tree of life. By delivering the Cas9 protein and appropriate guide RNAs into a cell, the organism's genome can be relatively cheaply cut at any desired location.
