How can we use this new information in teaching undergraduate A&P? Well, first we can update the numbers we use when discussing the role of genes in protein synthesis. If it fits with our course objectives, we can use this as a way to transition to a discussion of coding vs. noncoding genes.
We also have an opportunity to discuss how science works—we are constantly checking our facts and revising our conclusions to improve the accuracy of our knowledge. And that the story of genomics is far from complete.
I often tell students that I'm trying to tell them "the last, best story" of the human body's structure and function. So if my story changes over time, that's a good thing!
