Which characteristic does a virus have in common with a eukaryotic cell?

Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes. Once inside the cell, they use the cell's ATP, ribosomes, enzymes, and other cellular parts to replicate.
