Abstract
Gene editing technology is a technology that aims to change the sequence of target genes to achieve targeted mutation, insertion or knockout.As an emerging research field in the life sciences, the continuous development and improvement of gene editing technology provides a powerful tool for the functional research, gene detection and treatment of genes, which has greatly promoted the development of life sciences.This article first introduces the three main technologies in the development of gene editing technology—zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and CRISPR-Cas9.Through the modification of existing Cas9 nucleases and the search for new proteins with specific identification and cleavage sequences of interest, gene editing systems with a wider range of applications have been developed, driving the development of gene editing technologies.This paper also discusses the application and existing opportunities and challenges of gene editing technology to enhance the overall understanding of the technology and its future research.
