Key concepts

- 1
Viruses are not cells and are technically not classified as living things because they lack many characteristics of life.
- 2
All viruses have some type of genetic material, either DNA or RNA, and a protein coat called a capsid.
- 3
Viruses replicate by attaching to a host cell and injecting their genetic material, then using the cell's resources to make copies of the virus through the lytic or lysogenic cycle.
