Insertional Mutagenesis

Insertional mutagenesis is a technique used to identify genes and study their roles in living organisms. It involves introducing DNA into the genome of an organism in a random manner. This causes a random disruption of the function of the gene, which can then be studied. Insertional mutagenesis is a powerful tool for revealing gene functions, as it can identify novel genes that were previously not known to exist and uncover functions of known genes. It is also used in gene therapy techniques, allowing the addition or removal of a gene from the genome. This technique has been used to great success in areas such as cancer research and crops engineering.
