Higher Order Structure in Chromosomes

  • Chapter
Book cover International Cell Biology 1980–1981

Abstract

It is now well-established that histones interact with each other and with DNA to form nucleosomes, the invariant basic subunits of eukaryotic chromatin. Each nucleosome is a flattened disc, 55 Å × 110 Å, containing two molecules each of histones H2A, H2B, H3, and H4 in association with about 146 base pairs of DNA (for reviews, see Isenberg 1979; McGhee and Felsenfeld 1980). While our knowledge of the structure, composition, and properties of chromatin subunits is very detailed and at a high level of experimental sophistication, our understanding of the manner in which the basic chromatin fiber is folded to form higher order structures is fragmentary.
