摘要
The present invention includes compositions and methods for genome editing with in isolated cells or within an organism. The editing oligonucleotides contain an oligonucleotide strand which may contain a linker that positions an editing moiety in the proper location for modifying the targeted nucleobase and crisprRNA domain and an inactivated Cas 9 domain that cause deamination of the targeted nucleobase. The editing oligonucleotides may also contain at least one nucleotide sequence change from the targeted sequence in the genome. Certain embodiments of the method include modifying a genomic sequence within a cell utilizing an editing oligonucleotide without exogenous proteins to assist in the editing process. The editing oligonucleotide may comprise backbone modifications that increase the nuclease stability of the oligonucleotide as compared to unmodified oligonucleotides.
