Research Abstract	Faithful duplication and segregation of chromosomes are essential for cell proliferation. Replicated sister chromosomes are physically linked during their synthesis (sister chromatid cohesion), ensuring identification of chromosome pairs to be distributed into daughter cells. Although the cohesion establishment reaction cooperates with DNA replication, the mechanism how cohesion and replication couple remains unclear. In this study, we have examined how a DNA replication protein interacts with a cohesion protein using Xenopus egg extracts.
