Abstract

DNA computing has recently gained intensive attention as an emerging field bridging the gap between computer science and biomolecular science. DNA based computing can be competitively used to simulate various computing models including Boolean circuits because of its potential to offer massive parallelism. In this paper we present a new DNA-based evaluation algorithm for a bounded fan-in circuit consisting of AND and OR gates. The proposed model employs standard bio-molecular techniques. The main advantage of our method is that each level of circuit is capable of containing both AND and OR gates. It is shown that large bounded fan-in circuits can be simulated by the proposed approach with a logarithmic slowdown in computation time.
