We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it. Fast forward to modern day humans: science has revealed that less than 3% of the human genome is transcribed into messenger RNA (mRNA) molecules that in turn are translated into proteins. In contrast, 82% of it is transcribed into RNA molecules with other functions many of which still remain enigmatic.
