Remarkably, all the protein in all organisms is made by the catalytic activity of the RNA component of the ribosome, the cellular machine that reads genetic information and makes protein molecules.
—Jack Szostak, Scientific American, 1 June 2018
At the start of the animation, a ribosome (tan) is in the process of producing a connexin protein (aqua), based on information encoded in a messenger RNA molecule (purple).
—Karen Hopkin, Scientific American, 1 May 2015
So, for an lncRNA to escape the nucleus and give its instructions to a ribosome, the parental DNA must acquire those key U1 mutations or somehow make that transcribed section get cut out of the RNA strands altogether.
