Länk - RNA kan vara kroppens nätverksoperativsystem
Ever since the human-genome project was completed, it has puzzled biologists that animals, be they worms, flies or people, all seem to have about the same number of genes for proteins—around 20,000. Yet flies are more complex than worms, and people are more complex than either. Traditional genes are thus not as important as proponents of human nature had suspected nor as proponents of nurture had feared. Instead, the solution to the puzzle seems to lie in the RNA operating system of the cells. This gets bigger with each advance in complexity. And it is noticeably different in a human from that in the brain of a chimpanzee.
