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. This research focuses on further developing DNA-based methodologies to mimic digital data manipulation, demonstrating how information can be parsed through a circuit comprised of DNA-based dynamic logic gates. By dynamics we mean interactivity among the gates. A novel logic gate design based on chemical reactions is presented in which observance of double stranded sequences indicates a truth evaluation. An exemplifying application of our results, beside their fundamental significance, pertains to circuit security, providing for obfuscation and tamper-proofing. Furthermore, DNA-based dynamic logic gates enable ternary logic and the compression of circuitry.
