WebbGenome editing (GE) has revolutionized biological research through the new ability to precisely edit the genomes of living organisms. In recent years, various GE tools have been explored for editing simple and complex genomes. The clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 system has widely been used in GE due to its …
