DNA Tweezers Based on Semantics of DNA Strand Graph

Because of the limitations of classical silicon based computational technology, several alternatives to traditional method in form of unconventional computing have been proposed. In this paper we will focus on DNA computing which is showing the possibility of excellence for its massive parallelism, potential for information storage, speed and energy efficiency. In this paper we will describe how syllogistic reasoning by DNA tweezers can be presented by the semantics of process calculus and DNA strand graph. Syllogism is an essential ingredient for commonsense reasoning of an individual. This paper enlightens the procedure to deduce a precise conclusion from a set of propositions by using formal language theory in form of process calculus and the expressive power of DNA strand graph.
