One major difference between viruses and other cells is that viral particles have nucleic acid located within a capsid.
<h3>Structure of a virus</h3>
Viruses are made up essentially of ribonucleic or deoxyribonucleic acids enclosed in a proteinous shell known as capsids.
This is unlike other cells in which their nucleic acids either lie freely within the cytoplasm of their cells or are enclosed in a double membrane structure known as the nucleus.
Viruses are essentially non-living when outside a living host.
