Principle and applications of CRISPR/Cas system

Abstract

With the continuous in-depth research and exploration of the CRISPR/Cas9 system by researchers, people's ability to edit biological genes is also constantly improving. In recent years, gene editing technology as a hot technology has been paid more and more attention, it has played an important role in crop breeding, disease treatment, molecular diagnosis and other aspects. Among the gene editing technologies that have been developed, the emerging CRISPR/Cas technology gene editing system has become the most widely used gene editing technology at present. Compared with the first two generations of gene-editing technologies: ZFN and TALEN, CRISPR/Cas system has the advantages of short cycle, high efficiency, low cost, and has great potential for the development of animal and plant breeding. The development of CRISPR/Cas9 technology has promoted the progress of modern life sciences. With these tools for efficient, simple, and precise genome modification, transcriptional regulation, and epigenetic editing, CRISPR systems have the potential to revolutionize genetics, medicine, and agriculture. In this review, the basic principle of CRISPR/Cas technology and its application will be introduced and illustrated.
