Gene Therapy - GCSE Biology Definition

Gene therapy is a medical technique used to treat or prevent diseases by directly altering a person's genes. It works by inserting, removing, or changing specific genes within a person's cells to fix problems that cause illnesses. For example, if someone has a genetic disorder caused by a faulty gene, scientists may use gene therapy to replace it with a healthy version. This can help the body function properly and reduce symptoms. Gene therapy is still a developing field, but it holds great promise for treating a range of diseases, including certain genetic disorders, some types of cancer, and viral infections.
