The best example is the coding of amino acids AND a stop marker by sets of 3 DNA bases. However, there are more such as the coding for how to assemble different proteins from one gene and doubtlessly many more examples to be found in the future.
That is the actualization description I'm seeking for symbols. From what you have described, it appears the conditional operatives are encoded. IOW, the process, the databasing (learning), the acquisition of data, the self-replication, the conditionals and their operatives are all encoded serially.
How could anyone believe such encoding resulted by chance?
