What type of microbe is used to deliver gene therapies to human cells?

• A. Bacteria
• B. Fungi
• C. Virus
• D. Parasite

Answer: (C)

The correct answer is a virus. Viruses are often engineered or modified to serve as vectors for gene therapy due to their natural ability to enter host cells and deliver genetic material directly into the cellular environment. This attribute makes them particularly useful for transferring therapeutic genes to replace defective or missing ones in human cells.

In gene therapy, viral vectors can be designed to minimize potential adverse effects while maximizing their efficiency in gene delivery. Viruses such as adenoviruses, lentiviruses, and adeno-associated viruses are commonly employed because they can infect human cells and facilitate the uptake of the gene of interest, thereby promoting its expression and allowing for potential treatment of various genetic disorders.

Utilizing viruses for gene therapy takes advantage of their biological mechanisms, which have evolved to efficiently deliver their genetic material into host organisms. This capability is not typically present in bacteria, fungi, or parasites to the same extent or in the same context of direct gene delivery, making viruses the preferred choice in this area of biomedical research and application.
