Typogenetics was originally devised as a formal system with operations on DNA strands. It was recently demonstrated to be an effective model on which to study the emergence of self-replication by Kvasnicka et al.’s work. We make several extensions and variations on their work. The way of measuring difference and similarity between strands are improved. Many different mappings between doublet codes and their enzyme functions are tried. Triplet codes are also introduced. Through various experiments we observe frequent emergence of autoreplicators. We also find that emergence of self-replicators are robust phenomenon under various environments in typogenetics.
