"Virus" circa 2002 : Inspired by a paragraph I read in an old Time Life book (The Cell) explaining the basic attack mechanism of a virus. The quote below is not the original text that inspired the animation but the essence of it is close enough:
"Viruses that attack bacteria were named 'bacteriophages'. The term phage originates from Greek phagein, which translates as 'to eat'. The phage infection cycle seems to be simple but extremely efficient: a single phage injects its genome into a bacterial cell, switching the cells' programme in its favour so the host cell will eventually die and release about 100 new phage particles.1 "
