WebOct 7, 2024 · Gene knockout (GO) is a genetic technique supplemented with biotechnological tool, in which an organism is engineered to carry gene that has been made inoperative. These genes are known as knockouts; used in assigning function to specific genes having unknown function. Gene knockouts (also known as gene deletion or gene inactivation) are a widely used genetic engineering technique that involves the targeted removal or inactivation of a specific gene within an organism's genome. This can be done through a variety of methods, including homologous recombination, CRISPR … See more Knockouts are accomplished through a variety of techniques. Originally, naturally occurring mutations were identified and then gene loss or inactivation had to be established by DNA sequencing or other methods.
