Test your understanding of the living world with this simple question. What kind of large biomolecule is found in all living organisms? If your answer is “DNA”, you are incorrect. Many organisms contain no DNA at all.
The mistake is very forgivable though. A standard biology education casts DNA (DeoxyriboNucleic Acid) as the master molecule of life, coordinating and controlling most, if not all, living functions. This master molecule concept is popular. It is plausible. It is taught in every university and high school. But it is wrong. DNA is no master controller, nor is it even at the centre of biology. Instead, science overwhelmingly shows that life is self-organised. The science of biology is thus awaiting the paradigm shift to end all paradigm shifts. More
