who invented DNA?

We've heard before about the theory that life started out with catalytic RNA to eventually give rise to the DNA->RNA->protein system. This frenchie argues that viruses invented DNA as a way to evade host deffense. Eventually the enzymes to make DNA and the machinery to replicate it was adopted by the cells. Interresting theory, I always thought that Watson and Crick invented DNA...

I actually read a book on viruses and evolution where this guy thinks that virtually everything origonated in viruses, including the nucleus and all organelles. ie the nucleus I guess means DNA as well, I can't remember.
