Before revision:  potential between successive monomers, as well as the block lengths m and n and the repeat unit p (N=m_pn_p)  . We demonstrate that the due to change in the entropic barrier and the inhomogeneous friction on the chain  a variety of scenario are possible amply manifested in the incremental mean first passage time (IMFPT) or in the waiting time distribution of the translocating chain.
