DNA involves control flow, instructions, and stored state to produce a highly complex output from basic inputs and a complex control program (i.e. the DNA sequences, which constitute software). DNA and its software expressed as sequences constitute a full Turing Machine, capable of arbitrary computation. Actually, DNA is far more capable than a basic Turing machine.
There is strong interest in DNA computation in areas of theoretical computer science because classes NP-complete problems can be solved in polynomial time using DNA.
By your definition, a word-processing program is "just a template" for production of a wide variety of documents stored in a common format, given a sequence of keyboard and mouse inputs. According to your definition, there is no actual computation.
What is with today's Evolutionists, that they must continuously deny modern science's known facts about DNA?
