Several paradigm shifting advances have recently been made on the composition and function of the chromosomal DNA replication machinery. Replisomes appear to be more fluid and dynamic than ever imagined, enabling rapid and efficient bypass of roadblocks and template lesions while faithfully replicating chromosomal DNA. This fluidity is determined by many layers of regulation, which reach beyond the role of replisome components themselves. In fact, recent studies show that additional polymerases, post-transcriptional modifications, and chromatin structure are required for complete chromosome duplication. Many of these factors are involved with the more complex events that take place during lagging-strand synthesis. These, and other recent discoveries, are the focus of this review.
