Abstract:

CRISPR/Cas (Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated(Cas)) system is a DNA modified gene editing tools regulated by a kind of short RNA.This technology is a novel tool,which is more rapid,efficient and accurate than ZFN (zinc-fingers nuclease) and TALEN (transcription activator-like (TAL) effector nucleases) in genetic engineering.It is easy to be designed and has specificity.This paper reviews the structure and function of CRISPR/Cas9 system and the design strategy of Cas9 and its application in animal genetic engineering.CRISPR/Cas9 is successfully used in a variety of animal genetic editing,it is likely to become a new way to establish animal models and to develop a new feasible approach to prevent disease.
