gene disruption

Gene disruption, also known as gene knockout, is a technique in genetics where a specific gene within an organism's DNA is intentionally inactivated or disabled. This is achieved by introducing a foreign, non-functional DNA sequence that replaces the original gene.1

This process allows scientists to study the function of individual genes by observing the resulting changes in the organism's observable traits (phenotype). By creating "knockout" organisms, such as mice, researchers can gain insights into the biological roles of genes and their involvement in human diseases. Gene editing technologies, like CRISPR-Cas9, have made it possible to perform these precise modifications to DNA sequences, enabling targeted gene disruption. This has significant implications for understanding genetic diseases and developing potential therapies.234
