Before revision:  We quantify the degree of fluctuations in oscillation periods and amplitudes, as well as the noise propagation along the regulatory cascade using the exact stochastic simulations with the Gillespie algorithm in the stable oscillation regime  .
After revision:  We quantify the degree of fluctuations in oscillation periods and amplitudes, as well as the noise propagation along the regulatory cascade using the exact stochastic simulations with the Gillespie algorithm in the stable oscillation regime via dynamic Monte Carlo simulations .
