The Stochastic Evolution of a Protocell: The Gillespie Algorithm in a Dynamically Varying Volume

Figure 12

Fluctuation dependence on the initial conditions. We report the standard deviation of the protocell division time as a function of the initial amount of molecules 𝑋_𝑖(0), 𝑖=1,2, (•) and a linear best fit, whose slope is =−0.51±0.05. Parameters are 𝑋₁(0)=𝑋₂(0)=2^𝑛 with 𝑛=0,…,10, 𝐶(0)=10𝑋₁(0), 𝜂₁=𝜂₂=1, 𝛼₁=𝛼₂=2, 𝐿1=500, 𝐿2=500, 𝑃1=500, 𝑃₂=600, 𝜌=100, and 𝛽=1.
