Electron microscopy of defined lengths of chromatin

J T Finch et al. Proc Natl Acad Sci U S A. 1975 Sep.

Abstract

Defined lengths of chromatin were prepared by brief digestion with micrococcal nuclease and fractionation in a sucrose gradient. A length containing a given number of 200 base pair repeating units appeared as the same number of 100 A beads in the electron microscope. The distance between beads within a length was small, usually less than about 20 A.
