The nucleosome repeat length increases during erythropoiesis in the chick

Abstract

During erythropoiesis in the chick, the nucleosome repeat length increases from 190 base pairs to 212 base pairs. This increase is correlated with a dramatic increase in the concentration of the red cell specific histone H5 (from 0.2 molecules per nucleosome to 1 molecule per nucleosome) and with no change in the concentration of HI (1 molecule per nucleosome). © 1978 Information Retrieval Limited.
