Scroll to fly through a virus attacking a living cell — how it breaks in, takes over, builds copies of itself, and bursts out to start all over again.
A virus is a tiny invader that can't do anything alone, so it drifts through the body hunting for a cell, using its spike "keys" to find a matching door.
Locked on, the virus pushes its secret instruction booklet straight through the cell wall.
The virus's instructions push out the cell's own plans, so the cell only listens to the virus.
The hijacked cell becomes a factory, snapping together hundreds of brand-new viruses.
The stuffed cell bursts, and a swarm of new viruses flies out to find fresh cells and start again.
