Four applications are studied in detail: a nonlinear connection of two linear systems, the design of a logic pulse, a molecular amplifier and the interference of three signal generators in E2F1 regulatory element. The gene interactions are presented using molecular diagrams that have a precise mathematical structure and retain the biological meaning of the processes.45 pages, 14 figures, Excerpts from this manuscript were presented at the 3rd International Conference on Pathways, Networks, and Systems: Theory and Experiments, October 2-7, Rhodes Greece 2005.
