If the frictional force taken into the consideration (which depend on hydrodynamic size, shape of the molecule, pore size of the medium, & pore size of the medium) velocity, v , of a charged molecule in an electric field is therefore given by the equation

where f is the frictional coefficient.

Another example of a fail-safe system is a glycosylase that removes a T opposite a G. Such a T:G mismatch can arise, as we have seen, by spontaneous deamination of 5-methylcytosine,which occurs frequently in the DNA of vertebrates.
