What is gene therapy?

• A. A method for creating more efficient crops
• B. A technique that modifies or replaces faulty genes to treat or prevent disease
• C. A strategy for saving endangered species
• D. A way to enhance athletic performance

Answer: (B)

Gene therapy is a technique that modifies or replaces faulty genes to treat or prevent disease. This innovative approach aims to correct genetic defects that lead to diseases by directly targeting the gene responsible for the health issue. By introducing a healthy copy of the gene or repairing the defective gene, gene therapy can potentially restore normal function and alleviate the symptoms or effects of the disease.

The application of this technique is particularly significant in treating genetic disorders, certain types of cancer, and viral infections, where traditional methods may not be sufficient. The focus is on addressing the underlying genetic causes rather than merely managing the symptoms of the diseases. This specificity and potential for a long-lasting effect make gene therapy a groundbreaking area in modern medicine and biotechnology.

The other options represent different fields of biotechnology or applications that, while they are important, do not define gene therapy. For example, techniques to create more efficient crops are part of agricultural biotechnology and do not involve the direct treatment of genetic diseases. Strategies for saving endangered species may include genetic management, but this does not specifically relate to the therapeutic intentions of gene therapy. Similarly, methods aimed at enhancing athletic performance might involve other biotechnological practices, but they do not align with the primary goal of gene therapy, which is to correct or manage genetic
