What is the primary purpose of gene therapy?

• A. To replace defective or mutated genes with normal genes
• B. To enhance the genetic expression of existing genes
• C. To eliminate pathogens from the human body
• D. To create genetically modified organisms

Answer: (A)

The primary purpose of gene therapy is to replace defective or mutated genes with normal genes. This innovative approach focuses on addressing genetic disorders at the root level by introducing, removing, or altering genetic material within a patient's cells to treat or prevent disease. By replacing faulty genes with functional versions, gene therapy aims to cure genetic diseases or improve their symptoms, restoring normal cellular function. This method is particularly beneficial for conditions caused by single-gene defects, such as cystic fibrosis or some forms of muscular dystrophy. The goal is to restore the patient's ability to produce vital proteins or to regulate cellular processes properly, ultimately improving their health and quality of life. While enhancing the expression of existing genes, eliminating pathogens, or creating genetically modified organisms are important aspects of biotechnology and genetic engineering, they do not encapsulate the fundamental aim of gene therapy, which is specifically targeted at correcting genetic abnormalities in individuals.
