The structure of a virus consists of both (1) DNA and (2) Protein. So, the correct answer is (4) Both (1) and (2).

Here's a step-by-step explanation:

1. Viruses are microscopic parasites, generally much smaller than bacteria. They lack the capacity to thrive and reproduce outside of a host body.

2. Predominantly, viruses have a reputation for being the cause of contagion. Widespread events of disease and death have no doubt bolstered such a reputation.

3. The primary role of the virus is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell.

4. A fully assembled infectious virus is called a virion. The virion is composed of an outer protein shell called a capsid and an inner core of nucleic acid: either DNA or RNA.

5. The simplest viruses contain only enough RNA or DNA to encode four proteins. The most complex can encode 100 - 200 proteins.

6. Therefore, the structure of a virus consists of DNA (or RNA) and proteins, making option (4) Both (1) and (2) the correct answer.
