Illustration of a virus particle. A virus is an agent that can infect all types of life forms,replicating inside living cells. A virus particle (known as a virion) is made up of a protein outer shell,a capsid,which protects the genetic information inside. Viruses are too small to be visible with optical microscopes so scanning and transmission electron microscopes are used to visualise them. | |
