Educator's Guide

Viruses are the ultimate parasites. Lacking the cellular machinery required to produce additional viruses, they hijack the biochemical processes of the cells they infect. Once infected, a cell uses its own organelles to produce viral particles, which in most cases leads to the infected cell's death. With the discovery of Mimivirus, it now appears that viruses may have developed their simplistic form and replication strategy early on in the evolution of life, not as evolutionary latecomers that exploited a niche in host diversity. 02.07.2006
