Figure 12.

The diagram showing the random walk modeling along the protein interaction trajectories in the human interactome. A walk started from one of the youngest proteins (belonging to 17th phylostratum), taken randomly. This was the 1st protein. From all its interactants, one was chosen randomly (2nd protein), and the next step started already from this protein, again to a randomly chosen next interactant (3rd protein), and so on. The reverses to 1st and other previous proteins were allowed. The series of walks of a different length (from 5 to 10,000 steps) were tested.
