Nucleosomes function to tightly package DNA into chromosomes, but the nucleosomal landscape becomes disrupted during active processes such as replication, transcription, and repair. The realization that many proteins responsible for chromatin regulation are frequently mutated in cancer has drawn attention to chromatin dynamics; however, the basic mechanisms whereby nucleosomes are disrupted and reassembled is incompletely understood. Here, I present an overview of chromatin dynamics as has been elucidated in model organisms, in which our understanding is most advanced. A basic understanding of chromatin dynamics during normal developmental processes can provide the context for understanding how this machinery can go awry during oncogenesis.
