title: Mechanisms controlling the integrity of replicating chromosomes in budding yeast.
abstract: Cells are continually challenged by genomic insults that originate from chemical and physical agents diffused in the environment, but also normal cellular metabolism produces genotoxic effects. Moreover, DNA replication and recombination generate intermediates potentially dangerous for genome stability. Growing evidence show that many genetic disorders are characterized by high levels of chromosome alterations due to genomic instability, which is also a hallmark of cancer cells. Recent work shed some light on the molecular events that maintain the integrity of chromosomes during unperturbed S phase and in the face of odds.
