基于CRISPR/Cas9的精准基因编辑技术研究进展

Precision gene editing technologies based on CRISPR/Cas9: a review

摘要:

基因编辑技术是一种可以在基因组水平上对DNA序列进行改造的遗传操作技术。基于CRISPR/Cas9系统的精准编辑技术是一个操作方便、应用广泛的基因编辑技术，与传统的CRISPR/Cas9不同，精准基因编辑技术可以在不需要DNA模板的情况下对基因进行定点突变。本文重点介绍了近年来基于CRISPR/Cas9介导的精准基因编辑技术的发展，并深入分析了基因精准编辑技术面临的挑战和机遇。

Abstract:

Gene editing technology is a genetic operation technology that can modify the DNA sequence at the genomic level. The precision gene editing technology based on CRISPR/Cas9 system is a gene editing technology that is easy to operate and widely used. Unlike the traditional CRISPR/Cas9 system, the precision gene editing technology can perform site-directed mutation of genes without DNA template. This review summarizes the recent development of precision gene editing technology based on CRISPR/Cas9, and prospects the challenges and opportunities of this technology.
