Some scientists are researching how to manipulate viruses so as to be useful in nanotechnology applications, particularly in the human body. Since viruses do not engage in metabolic activity to survive and reproduce, they may be durable building blocks for composite materials. Viruses can be altered to serve human purposes through two approaches, chemical modification and genetic engineering. To make a virus into an effective nanotechnological structure, it is necessary to determine how to attach biological interfaces to the surface of the virus’s protein coat.

The discussion above most strongly supports which of the following statements?

Correct answer marked below

Research into nanotechnology is likely to produce useful applications in the human body.

Viruses are the best choice to make composite materials on a nanotechnological scale.

The protein coats of viruses naturally lack biological interfaces.

Composite materials are of interest primarily due to their potential uses in the human body.

For their research to be successful, scientists must figure out how to make attachments to the protein coats of viruses.
