Gene editing is a cutting-edge technology that allows scientists to make precise changes to an organism's DNA. This can involve adding, removing, or altering specific genes to create desired traits or characteristics. One of the most well-known gene editing tools is CRISPR-Cas9, which uses a protein and a guide RNA to target and cut specific sections of DNA. Gene editing has many potential applications in medicine, agriculture, and biotechnology, and has the potential to revolutionize the way we treat genetic diseases, develop new crops, and understand the fundamental mechanisms of life. However, there are also ethical concerns and regulatory challenges surrounding gene editing, particularly in the context of human germline editing.
