Question

1. which biotechnology application uses viruses to specifically attack areas of cell overgrowth? nanoparticle delivery cancer treatments vaccine development gene therapy

Explanation:

• Nanoparticle delivery: Focuses on using nanoparticles for drug or molecule transport, not specifically using viruses to attack cell overgrowth.
• Cancer treatments: Oncolytic viruses are a type of cancer treatment where viruses are engineered to specifically infect and destroy cancer cells (areas of cell overgrowth).
• Vaccine development: Aims to prepare the immune system against pathogens, not to attack existing cell overgrowth.
• Gene therapy: Involves introducing genes into cells to treat genetic disorders, not directly attacking cell overgrowth areas with viruses in the context of this question.

Answer:

B. cancer treatments
