_____ contain genetic material enclosed in a protein coat. They are obligate parasites

Explanation

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks for an organism that contains genetic material enclosed in a protein coat and is classified as an obligate parasite.

2. **Understanding Viruses**: The organism that fits this description is a virus. Viruses are unique in that they consist of genetic material (either DNA or RNA) surrounded by a protective protein coat called a capsid.

3. **Obligate Parasites**: Viruses are considered obligate parasites because they cannot reproduce independently. They require a host cell to replicate. Outside of a host, viruses are inert and do not exhibit characteristics of living organisms.
