A novel approach to design a reversible shifter circuit using DNA

Traditional silicon computers are believed to consume more power compared to computing systems based on Deoxyribonucleic Acid (DNA). In addition, DNA-based logic gates are stable, reusable and also outperform the non-DNA based existing shifters. In this paper, a new approach for designing DNA-based reversible shifter circuit is proposed where any kind of shifting operations can be carried out. The proposed DNA-based reversible shifter circuit is comparatively faster due to parallelism and replication properties of DNA strands. It also requires less space because of the compactness of DNA strands.
