I don't know. The concept of junk DNA never made sense to me because, besides proteins, you need to know how to assemble everything and when. The idea behind junk DNA was that the rest of it didn't code for proteins and therefore was junk. But if I give you a list of parts for a Boeing 747 that's not enough information to build the jet. I never understood how this was not obvious to scientists. I still remember being taught the concept of junk DNA in high school, and didn't believe it then.
