The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated nuclease 9 (Cas9) system from bacteria and archaea emerged recently as a new powerful technology of genome editing in vir-tually any organism. Due to its simplicity and cost effectiveness, a revolutionary change of genetics has occurred. Here, we summarize the recent development of DNA fragment editing methods by CRISPR/Cas9 and describe tar-geted DNA fragment deletions, inversions, duplications, insertions, and translocations. The efficient method of DNA fragment editing provides a powerful tool for studying gene function, regulatory elements, tissue development, and disease progression. Finally, we discuss the prospects of CRISPR/Cas9 system and the potential applications of other types of CRISPR system.
