Petri nets: an application in digital circuits

Synthetic biology has been used to describe an approach to biology which attempts to design and construct deliberate biological systems that can be investigated experimentally, which are otherwise very expensive and practically challenging. One of the central features of synthetic biology is the appreciation of the knowledge from science and engineering disciplines for the better design and understanding of synthetic networks. In this paper we will study regarding Petri nets and how digital circuits can be implemented using Petri nets. This paper highlights an emerging field known as synthetic biology that envisions integrating designed circuits into living organisms in order to instruct them to make logical decisions based on the prevailing intracellular and extra cellular conditions and produce a reliable behavior. The networks in a system can be dissected into small regulatory gene circuit modules. Synthetic biology attempts to construct and assemble such modules gradually, plug the modules together and modify them, in order to generate a desired behavior. Using biological circuit, we can produce a new concentration gradient that has twice the frequency. If '1' is represented by a concentration of the chemical within the threshold, and a '0' is represented by a concentration outside the threshold, then we can represent any two digit binary number. Thus, we can differentiate separate regions at certain distances away from a point source. In this paper we will discuss how to make Logic gates (AND, OR, NOT) using Petri net. Using this approach we can design any Boolean equation
