Chemical mutagens can be divided into two groups:

those that are mutagenic to both replicating and nonreplicating DNA, such as the alkylating agents and nitrous acid; and 

those that are mutagenic only to replicating DNA, such as base analogs— purines and pyrimidines with structures similar to the normal bases in DNA.

The rate of sedimentation is dependent not only upon the applied centrifugal field, but
also on the nature of the particle, i.e., its density and radius, and also the viscosity of the
surrounding medium. Stokes’ Law describes these relationships for the sedimentation of a
rigid spherical particle:
