Abstract

The organization of interphase chromatin spans many topics, ranging in scale from the molecular level to the whole nucleus, and its study requires a concomitant range of experimental approaches. In this review, we examine these approaches, the results they have generated, and the interfaces between them. The greatest challenge appears to be the integration of information on whole nuclei obtained by light microscopy with data on nucleosome-nucleosome interactions and chromatin higher-order structures, obtained in vitro using biophysical characterization, atomic force microscopy, and electron microscopy. We consider strategies that may assist in the integration process, and we review emerging technologies that promise to reduce the "resolution gap."
