← Researchers Discover Remnant of an Ancient 'RNA World'

Shane McKee's Avatar Jump to comment 6 by Shane McKee

It's intriguing stuff, but not unexpected at all. In a lot of ways, we still *are* RNA organisms. The "DNA world" is something of an illusion. DNA's just the hard-drive; much of the real work is done by RNA. We've got used to thinking of RNA as a mere intermediate between DNA and proteins, but it is so much more than that, as we're now discovering - most of the cellular metabolism (and even genetics) that we used to think was fundamental is froth on the top. Look deeper, kids :-)
