Transgenesis involves introducing foreign DNA into the fruit fly genome. This can be done by injecting DNA into the developing embryo or by using a virus to deliver the DNA. The foreign DNA can then be incorporated into the fly’s genome, allowing it to express the new gene. Transgenesis is used to study the function of specific genes or to create fruit fly models of human diseases.
6.2. Gene Knockout
Gene knockout involves deleting a specific gene from the fruit fly genome. This can be done using a technique called homologous recombination, which involves replacing the target gene with a non-functional copy. Gene knockout is used to study the function of the deleted gene and to investigate its role in development, behavior, and disease.
6.3. CRISPR-Cas9 Gene Editing
CRISPR-Cas9 is a powerful gene editing technology that allows scientists to precisely modify genes in fruit flies. The CRISPR-Cas9 system consists of two components: a Cas9 protein, which acts as a molecular scissor, and a guide RNA, which directs the Cas9 protein to the target gene. The Cas9 protein cuts the DNA at the target site, and the cell’s repair mechanisms then repair the break. Scientists can use this system to introduce specific mutations, delete genes, or insert new genes into the fruit fly genome.
