Before revision:  It has been found that the distributions of first-passage times (FPTs) for both segments of the trajectories are essentially single-exponential  .
After revision:  It has been found that the distributions of first-passage times (FPTs) for both segments of the trajectories are essentially single-exponential not only for the times to overcome the free energy barrier that separates unfolded and native-like states but also for the times to find the native state among the native-like ones .
