Unjunking More "Junk" DNA
Years ago, the human genome was ineffectively sequenced. Toplofty scientists, reasoning from their molecules-to-molasses preparer evolutionary presuppositions, determined that the things they didn't understand were "junk" from our alleged evolutionary past. Using more advanced equipment and using due diligence, most of the things that were labeled as non-functional have been both embarrassing and surprising, since they do have functions, some of them very intricate. Herein lies an example of how evolutionary thinking hinders science. If the previous sequencers had assumed instead that life was created, and what was found was there for a purpose, there would not have been so many delays in scientific advancement.

I'll allow that it's difficult to find something that is difficult to see, and further discoveries were practically hiding in plain sight. They're small, but have vital roles, including finding damaged DNA, performing "triage", and then stepping back when DNA repair help arrives. We continually see the specified complexity from the brilliant work of our Creator.
Molecular biologists are finding a universe of functional small proteins and RNAs that were considered junk or not even known to exist.To finish reading, click on "Small Molecules Play Key Roles in Cells".
We often hear that 98% of the human genome is “noncoding” for proteins. This may be a very misleading statistic. Actually, most of the genome is transcribed into RNAs, whether or not those result in the large proteins we know about. Hidden in those transcripts are small molecules known as micro-RNAs, and some longer ones known as “long non-coding RNAs” (lncRNAs) that are increasingly seen as vital in gene regulation. And now, scientists are beginning to uncover transcripts that are translated into protein fragments. Too small to be called proteins, these polypeptides also play vital roles in cell health. The genes that program these small molecules, once dismissed as “junk DNA,” are revealing more sophistication in the genome than previously thought.
