Quick student answer
Which of the following correctly describes the structure of a virus?
Direct answer
A virus is composed of genetic material surrounded by a protein coat.
Key terms
- Viral genome: The genetic material of a virus, which can be either DNA or RNA, and carries the information necessary for viral replication.
- Capsid: The protein shell that surrounds and protects the viral genome, composed of protein subunits called capsomers.
Common trap
Confusing viruses with bacteria: Remember that viruses are acellular and lack the structures found in living cells, such as membranes and organelles.
