      So we probably have around 25,000 protein coding genes, whilst these are the most important genes we have they are not the only type, there are ones that stay as RNA (many different kinds) and lots of regulatory elements. Only around 1-2% of the human genome is made into proteins, but the rest is not useless, we just don’t know what it all does yet.
