There are finite genetic differences between organisms that explain their differences and how closely they are related. The universal code means that these differences affect organisms in specific ways that explain the relationships between them. The universal code is strong evidence that all living organisms have a common ancestor: if this were not the case, different genetic codes in different organisms would be expected. The universal code means that organisms interpret a gene sequence in the same way, so the same protein is produced is a gene is placed in a different organism. The universality of the code does not directly affect transcriptional and translation regulation, which differ between organisms.
