Gene Editing
Gene editing represents a transformative approach in biological science, allowing for the precise alteration of DNA sequences within a living organism. By utilizing enzymes that act as molecular scissors, researchers can delete, add, or replace specific segments of the genetic code to study gene function and address mutations.
The biochemical process typically involves a guide RNA that identifies a specific sequence, followed by an enzyme like Cas9 that creates a double-strand break. This activation of the cell’s natural repair mechanisms allows for the introduction of desired genetic changes, offering a path toward permanent solutions for inherited disorders.
Beyond simple corrections, gene editing is being explored for its potential in creating disease-resistant cell lines and enhancing the production of therapeutic proteins. In the context of oncology, researchers are using these tools to engineer immune cells that are more effective at recognizing and eliminating malignant tissues. The precision of these systems reduces…
