DNA repeat size in chick embryonic lens epithelium, lens fiber, brain and liver cell nuclei

A S Muel et al. Cell Differ. 1985 Jun.

Abstract

The DNA repeat size is determined by micrococcal nuclease digestion kinetics and subsequent electrophoresis of the products among various chick embryonic tissues. The repeat size is found to be not significantly different from 193 to 197 bp, for brain and liver at 11 days and for lens epithelium and fiber at different embryonic stages. However, the pattern of micrococcal digestion seems to reveal an overall chromatin modification as a function of development in the lens fibers.
