Regulated helicase activation by DDK kinase is central for genome stability. However, how DDK phosphorylation primes the MCM2-7 double hexamer (DH) for Sld3-Sld7 binding and Cdc45 loading remained ...

Brandt Eichman and Walter Chazin, professors of biochemistry, have worked together to provide a better understanding of how exactly DNA replication is initiated in eukaryotes. Using Vanderbilt's state ...

Eukaryotic DNA replication relies on a highly orchestrated series of events centred on the Cdc45–MCM–GINS (CMG) helicase complex. Origin licensing begins in G1 phase with loading of a double hexamer ...

The research published in Nature on Dec. 25th, 2019, led by Dr. LI Guohong and Dr. ZHU Mingzhao from the Institute of Biophysics of the Chinese Academy of Sciences, has demonstrated that the histone ...

E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible. “It’s as ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
