## Abstract The role of histones and higher order chromatin structures in protecting against oxidative DNA damage was investigated using an in vitro system consisting of nuclear and nucleoid monolayers as model chromatin substrates. These substrates, derived from human skin fibroblasts, were challe

โฆ Synopsis
Recently, there has been a convergence of fields studying the processing of DNA, such as transcription, replication, and repair. This convergence has been centered around the packaging of DNA in chromatin. Chromatin structure affects all aspects of DNA processing because it modulates access of proteins to DNA. Therefore, a central theme has become the mechanism(s) for accessing DNA in chromatin. It seems likely that mechanisms involved in one of these processes may also be used in others. For example, the discovery of transcriptional coactivators with histone acetyltransferase activity and chromatin remodeling complexes has provided possible mechanisms required for efficient repair of DNA in chromatin.
