DNA contains computational control structures like conditionals and loops
DNA regulation naturally functions through mechanisms analogous to computational control structures, allowing researchers to engineer genetic circuits that perform logic operations, conditionals, and loops.
The retrieved papers consistently demonstrate that biological regulatory elements in DNA (such as promoters, operators, transcription factors, and feedback loops) can be analyzed and engineered as computational control structures, including logic gates, switches, and feedback mechanisms. The evidence strongly supports the claim that DNA contains these regulatory analogs.
