You think DNA isn't a language? That seems... restrictive. To me, the term language was genericized from "how people talk to each other" to "sequences of tokens which convey information in semi-standardized forms between information-processing entities". DNA uses the metaphors of language- the central dogma of biology includes "transcription" (copying of DNA to RNA) and "translation" (converting a sequence of RNA to protein). Personally I think those terms stretch the metaphor a bit.
