Eukaryotic cells also have type I and type II topoisomerases. The type I enzymes are topoisomerases I and III;

The eukaryotic type II topoisomerases cannot underwind DNA (introduce negative supercoils), but they can relax both positive and negative supercoils.

Algebraic transformation of the exponential correlation into an expression based on the decadic logarithm yields the law of Beer–Lambert:

where [d] = 1cm, [c] = 1mol^dm -3 , and [e] = 1dm^3mol -1 cm1 e is the molar absorption coefficient.
