2010	Modeling genome-wide replication kinetics reveals a mechanism for regulation of replication timing Scott Cheng-Hsin Yang, Nicholas Rhind and John Bechhoefer Molecular Systems Biology 6, 404 (2010) [PDF][Supplementary Material] Selected for Faculty of 1000 Biology (evaluated by Olivier Hyrien): In this remarkable paper, the authors provide a general analytical formalism for DNA replication kinetics and apply it to microarray data to extract the firing-time distribution and efficiency of most replication origins in the Saccharomyces cerevisiae genome. They find that earlier firing origins have tighter control of their initiation timing and higher efficiency than later firing origins and that this trend may be simply explained by the number of minichromosome maintenance (MCM) complexes loaded at each origin, without invoking an explicit time-counting mechanism. Thus, temporal patterns in replication can arise through stochastic initiation.
	Defects and DNA replication Michel G. Gauthier, John Herrick and John Bechhoefer Phys. Rev. Lett. 104, 218104 (2010) [PDF] Selected for a Synopsis in Physics : Copying DNA despite defects Selected for Faculty of 1000 Biology (evaluated by Arach Goldar): The authors demonstrate in an elegant and quantitative manner that the observed correlation between origin firing density and replication fork speed could be the result of fork stalls. This original work reveals the role of replication forks in regulation of DNA replication.
