Constructing DNA Full Adder Circuit Based on the Simple and Efficient AND Logic Blocks

This work presents the design and implementation of a DNA-based full adder circuit constructed using simple and efficient AND logic blocks. With the growing demand for alternative computing paradigms beyond conventional CMOS technology, DNA computing has emerged as a promising approach due to its inherent parallelism, low power consumption, and high data storage capability. In the proposed design, basic logic operations are realized through DNA strand displacement and hybridization processes, where AND logic blocks act as the fundamental building units. The full adder circuit is developed by integrating these AND-based modules with complementary logic structures to generate accurate sum and carry outputs. The proposed architecture focuses on reducing reaction complexity, minimizing the number of DNA strands, and improving computational reliability. Simulation and theoretical analysis demonstrate enhanced efficiency, lower error rates, and reduced biochemical reactions compared to existing DNA-based logic circuits. This design is highly suitable for applications in molecular computing, bio-sensing systems, and nano-scale information processing.
