DNA is too complex to have formed in the first organism. Abiogenesis is a complex subject, here is a good video explaining it.

This news item - http://www.thenakedscientists.com/HTML/content/news/news/1710/ - describes the work of chemist John Sutherland, who has been working out how nature came up with genetic "letters" in the first place...
