title: 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 H1 (1 molecule per nucleosome).
