Single Base Editing Is Now Possible With CRISPR Splice

WebBase editors have two principal components: A CRISPR protein, bound to a guide RNA, that leverages the established DNA-targeting ability of CRISPR, but modified to not cause a double-stranded break. A base editing enzyme, such as a deaminase, which carries out the desired chemical modification of the target DNA base. WebCRISPR also utilizes single base-pair editing proteins to create specific edits at one or two bases in the target sequence. CRISPR/Cas9 was fused with specific enzymes that initially could only change C to T and G to A mutations and their reverse. ...
