Conditional gene knockout is a technique used in molecular biology to study the role of a specific gene in a living organism. It involves the targeted deactivation of a gene in a specific tissue or at a specific developmental stage. Synonyms for the term "conditional gene knockout" include conditional gene deletion, inducible gene knockdown, and targeted gene inactivation. These techniques are widely used in research to study the functions of genes and their involvement in disease processes. Conditional gene knockout approaches are a powerful tool to understand gene function in cells and organisms, with applications in fields such as biotechnology, agriculture, and medicine.
