Incorrect Application of Gene Therapy

Steps:

• Review option A: Genetic engineering creates transgenic animals for xenotransplantation.
• Review option B: Gene therapy addresses genetic disorders, not infectious agents.
• Review option C: Recombinant techniques produce human proteins in microbes.
• Review option D: GM crops incorporate traits for pest resistance and yield improvement.

Why B is correct:

• Gene therapy modifies patient genes to treat inherited conditions, per its definition by the American Society of Gene & Cell Therapy; it does not prevent bacterial infections, which rely on immunity or antimicrobials.

Why the others are wrong:

• A: Accurate; labs engineer pigs for compatible transplant organs.
• C: Accurate; E. coli bacteria synthesize insulin via inserted human genes.
• D: Accurate; CRISPR and other tools create pest-resistant, enhanced plants.

Final answer: B
