Structure is function.
I reiterate, not snark, fundamental.
Let's look at the entire paragraph: -- Not really. Yes, estimates of "junk DNA" have been reduced from maybe 90% to something less, but alleged functions of most "junk" are not, as yet, determined, and the fact remains that most mutations within the "junk DNA" regions have no discernable affect on offspring. -- It's gibberish. Hand waving empty rhetoric and non-sequitur.
Only to someone whose normal language is not American-English, you know, the kind we talk here at Free Republic?
Maybe you need to go back to school and learn to translate your language of science to real English?
I'd be interested, especially if they teach you to drop the snarky nonsense.
