    Modern scientific consensus is largely that “junk” DNA isn’t a thing. All of our DNA has purpose including and sometimes especially the non-coding(nc) parts. The ncRNAs made from ncDNA come in various flavors and are very important to a lot of gene expression control. As seen here that’s ETS2 but pretty much all known genes have ncRNA that affects expression in one way or another.

    Biology at a research level has basically had to throw out the DNA->RNA->protein dogma because they all affect each other and themselves.

      Well, there’s things like “jumping genes” that don’t necessarily provide anything for the organism, but that’s a bit of a nitpick, since they’re not just random codons, and some do or at least could.
