Viruses have several unique features that distinguish them from living organisms. They are acellular, meaning they lack cellular structures and cannot reproduce independently; they require a host cell to replicate. Viruses consist of genetic material (either DNA or RNA) enclosed in a protein coat called a capsid, and some have an additional lipid envelope. Their ability to evolve rapidly and adapt to host defenses is another notable characteristic, contributing to their diversity and complexity.
