Before revision:  Our study shows that the onset of glassy dynamics is the reason for the formation of URLanization in human chromosomes (N\approx 3\times 10^9, \phi\gtrsim\phi_c^{\infty}), whereas chromosomes of budding yeast (N\approx 1.2\times 10 ^7 , \phi<\phi_c^{\infty}) are equilibrated with no clear signature of URLanization.
