A Search for the Physical Basis of the Genetic Code. Genetic code is one of the greatest mysteries of biology: it is shared by basically every living organism on this planet, with little to none differences between species that can be very far away from each other from an evolutionary point of view. Not only organisms share similar DNA structures and protein synthesis methods: the translation from a base triplet to the respective amino acid, i.e the genetic code, is found to be surprisingly consistent among all living creatures. The genetic code is not only stable between different species, but also through millions of years of evolution: it has been almost identical to itself for a very long time.
