When the MCM motor of the replicative helicase becomes loaded onto chromatin, origin DNA is licensed for replication. Here, the authors show why the ATPase function of MCM is needed in this process. Powered by ATP hydrolysis, MCM steps away from its own loader, tracking along both DNA strands...

The Replication Fork is forms with the Leading and Lagging strands. Step 5 In the leading strand, RNA Primase moves along nucleotides and coats with a RNA Primer that will be used as a homing beacon for the DNA Polymerase. Step 6
DNA replication is the production of identicalDNA helicesfrom a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a...
一、由单链断裂导致的复制叉坍塌(replication fork collapse)或由DNA复制受阻导致的复制叉断裂(replication fork breakage)是造成DSB的重要原因(复制叉坍塌或断裂几乎在E.coli的每个细胞周期中都会自然发生。在静止期E.coli中,复制叉可以R环为基础组建,并可在基因组中常见的自发单链断裂处坍塌。)。单链断裂可由单链...
Nuclear Pore complexes (NPCs) act as docking sites to anchor particular DNA lesions facilitating DNA repair by elusive mechanisms. Using replication fork barriers in fission yeast, we report that relocation of arrested forks to NPCs occurred after Rad51

Cells were washed twice with ammonium carbonate (75 mM, pH 7.4) before two 10-min incubation steps with extraction buffer (40:40:20 v/v/v acetonitrile/methanol/water containing 10 ng ml−1 13C10-ATP as an internal standard (Sigma, catalogue no. 710695)) at −20 °C. The...
