DNA condensation and gene regulation

Most nowadays descriptions of gene adjustment are based on the approximations of calm bounden in adulterate solutions, although it is bright that these assumptions are in actuality abandoned in chromatin. The dilute-solution approximation is abandoned for two reasons. First, the chromatin agreeable is far from actuality dilute, and second, the numbers of the accommodating molecules are sometimes so small, that it does not accomplish faculty to allocution about the aggregate concentrations. Further differences from adulterate solutions appear due to the altered bounden affinities of proteins to abridged and uncondensed DNA. Thus in abridged DNA both the acknowledgment ante can be afflicted and their assurance on the concentrations of reactants may become nonlinear.1
