Genetic editing, also called genome editing is an area of scientific research concerned with the modification of genes of living organisms to better understand its function or to cure diseases. Gene editing is performed using enzymes, particularly nucleases that have been engineered to target a specific DNA sequence, where they introduce cuts into the DNA strands, enabling the removal of existing DNA and the insertion of replacement DNA. The most commonly used genome editing systems are clustered regularly interspaced short palindromic repeats and its associated proteins 9 (CRISPR/Cas9), transcription activator-like effector nucleases (TALENs), zinc-finger nucleases (ZFNs), and homing endonucleases or meganucleases.
