Gene therapy. Conceptual computer artwork of drug capsules filled with DNA (deoxyribonucleic acid), to depict gene therapy 'pills'. Gene therapy is the genetic treatment of medical conditions caused by malfunctioning genes. The DNA helices in the image represent the corrected gene, which will allow the person taking the capsules to function normally. The foetus in the pill (right) may represent the prenatal diagnosis of a genetic defect, such as cystic fibrosis, and gene therapy being applied to the foetus to remedy its condition before it is born.
