Yeah... We know now that environmental factors change how DNA is expressed as well through epigenetics. I don't know how any of it works. Something to do with the shape the DNA when it is wound up and how it changes the output when RNA produces proteins. This is how parents can do things like pass some of the athleticism they earn through training to their children. It is possible for athletic parents to pass genes in such a way that it produces children even more athletic then they were. All of this means that DNA has the ability to encode information and produce proteins in different ways using the same sequences. So I am guessing that a lot of the DNA that is considered "junk" may not actually be. They are just missing a piece of the puzzle in how it gets read in.
