The code is universal in general construction and function, but is unique for every organism in existence. This universality and irreducible complexity is the intelligent design of God, who alone could design and create what is the multi-level coded, homochiral structured, most complex information system in the universe.
RNA self-replicating? Only in naturalist's imaginations and fantasies. RNA is an intermediate molecule produced by DNA to perform a number of cellular functions. It is highly reactive, and mutatable. The wide array of RNA lab experiments are intelligently designed to fabricate modification that have added additional functionality, replication not included. It requires distinctive amino acids that are all homochirally formed, which does not occur naturalistically.
It is the uniqueness of selected amino acid sequences and how they are folded and formed that defines the function of all organic assemblies, whether enzymes, RNA, proteins, or ribosomes. All the amino acids are uniquely defined in DNA and all are homochiral. Because of the common design of genetic systems in many organisms, they are generally, but not necessarily universally identical.
Cytochrome-C proteins in chimpanzees and humans are due to common design not common descent. Ostensibly, 50% of human genetic code is similar to turnips, not due to common descent.
