Knockout research involves the deliberate disruption or deletion of a specific gene or protein in order to study its function or impact on an organism. This can be done in a variety of organisms, such as mice, fruit flies, or plants, and is commonly used in molecular biology and genetics research to understand the role of specific genes in biological processes, development, diseases, and other aspects of biology. Knockout research is a valuable tool for elucidating gene function and identifying potential targets for therapeutic interventions.
