Gene editing method using virus

Abstract

Provided is a method of inserting a polynucleotide sequence into a genome of a cell. The method comprises: generating a double-strand break at a target site of the genome; and introducing into the cell a virus. The virus comprises a nucleic acid comprising the polynucleotide sequence to be inserted or the complementary sequence thereof. The nucleic acid does not comprise a homologous arm or comprises very short (5˜25 bp) homologous arms corresponding to the target site. Also provided herein is a composition for inserting a polynucleotide sequence into a genome of a cell. The composition comprises a site-specific nuclease capable of generating a DNA double-strand break at a target site of the genome and a virus comprising a nucleic acid comprising the polynucleotide sequence or the complementary sequence thereof.
