A role for "junk DNA"

Maybe, but don't forget there are regions of highly conserved introns.

Oh yes, I realize that. I was referring to "actual junk DNA," wondering if the DNA that doesn't serve any other purpose at all might be useful mutation fodder, and thus preserved in the genome.

Zombified: You can remember that exons are the coding sequences by thinking of the word exhibited. Introns are the noncoding sequences. Well, at least that's how I remember it.

And here we thought the Human Genome Project was done.
