Abstract
Replicating chromatin is known to be more sensitive to micrococcal nuclease than bulk chromatin. We have used this property and a fractionation procedure based on the specific release of replicating material under mild micrococcal nuclease digestion, in order to analyse both the kinetics of maturation of newly replicated DNA into nucleosomes and the structure of the replicating material. As other authors, we initially observed that repetitive unit of newly replicated chromatin was shorter than that of bulk chromatin, however this result appears to be due to sliding of nucleosomes along the chromatin fibers close to the replicating fork. Replicative chromatin was fractionated and analysed. A prenucleosomal peak was observed and preliminary characterized.
