maybe Im not understanding this correctly, but from the way I read it, a virus on its own cannot reproduce, there has to be a full (DNA) based cell for it to infect or take over. A virus is like a parasite, it cannot exists (spread) by itself - it needs the higher lifeform (the DNA cell) to propagate

or am I missing something?
