A recent motivation on the analysis and computation of stochas-tic chemical kinetic systems arises from the stochastic modeling of Gene Regulatory Networks in living cells. The synthesis of cellular proteins is a multi-step process. The genetic information stored in DNA directs the production of proteins through a process called gene expression [7]. When a specific gene is expressed, its DNA is first transcribed into a single strande
