Gene Editing

Gene editing technology is a set of advanced molecular biology tools that directly modify the genome of an organism, such as the CRISPR-Cas9 system. Through gene editing, genetic information of organisms can be selectively inserted, deleted, or modified to achieve precise control of gene expression. Gene editing technology also raises ethical and safety issues, so scientists and policymakers need to carefully weigh and regulate its use in practical applications.

Related Experimental Schemes

  • Gene editing modify specific sites within the genome through gene deletions, insertions or conversions to study functionally unknown genes or conduct gene therapy. It is also used to change the biological traits of organisms to establish new varieties. Gene editing techniques include zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas 9) (CRISPR/Cas9).
