Our deterministic model is the best option to represent our system because we assume that all the variables behave continuously and obey kinetic rules, in other words, there is nothing that it is going to disturbed our system and we don´t take account other variables. Also, it is perfect to model our equations that represent the production of mRNA and proteins of cI, Vip3Ca3, and GFP of each respective part of our system and have something precise with the parameters that we get and the graphics that represent the behavior. The probability equation it is still in development but we are trying to figure out how the thermo sensor can affect besides the control of temperature that control our system. We have to understand that this is not an excellent representation, this is only a way to understand how act and some assumptions that we think is the best option.
