Paul Andersen describes the important characteristics of viruses. He starts with a brief description of origin theories. He then describes the two characteristics of all viruses; genetic information and protein coats. He also describes how some viruses use specialized envelopes to gain entry to their host cells. He also explains the lytic and lysogenic reproductive cycles.
