DNA computing is an emerging field of research in which biochemistry and molecular biology elements are utilized to complete computational processes performed by traditional silicon-based technologies. Current DNA-based circuits are non-homogenous, consisting of discrete combinatorial gates with corresponding static processing abilities. This research focuses on further developing DNA-based methodologies to mimic digital data manipulation. Homogenous logic design principles are introduced, laying the foundations of dynamic processing whereby information can be parsed through a digital circuit comprised of DNA–based logic gates. The ultimate aim would be to facilitate shift-and-add calculation. More immediate applications concern data tamper-proofing, serving security needs whose progress was previously limited. A novel logic gate design based on chemical reactions is presented in which observance of double stranded sequences indicates a truth evaluation. Circuits are obfuscated by removing of physical sequence connections, allowing client-specific representative strands for input sequences, altering the input sequence strands over time, and varying the input sequence length.
