Q: A virus is essentially dna or rna surrounded by a coat of what?


Read this paragraph and choose the correct option from the provided answers:

The answer is actually “no. ” A virus is essentially DNA or RNA surrounded by a coat of protein ( Figure below ). It is not made of a cell , and cannot maintain a stable internal environment ( homeostasis ). Recall that a cell is the basic unit of living organisms. So if a virus is not made of at least one cell, can it be living? Viruses also cannot reproduce on their own—they need to infect a host cell to reproduce. So a virus is very different from any of the organisms that fall into the three domains of life.

 Choices:

- acids

- paint

- organism

- protein

protein
