DNA replication and genome stability
The creation of two identical copies of the genome is the defining event of life, essential for cell division. This process takes place during Synthesis-phase of the cell cycle. DNA replication is a very stressful event, as mistakes can lead to mutations and any obstacle on the way of the replication machinery could cause irreparable damage. Problems during DNA replication are the most frequent initiating events in cancer development. To control the fidelity of this process cells have evolved checkpoint mechanisms. Moreover, DNA replication itself is highly organized, both spatially and temporally inside the nucleus. While the function of numerous proteins has been elucidated in the monitoring of replication and in the signaling of arising problems, very little is known about the factors involved in the spatio-temporal organization of the DNA replication process.
