The initiation of eukaryotic DNA replication

A Costa, JFX Diffley - Annual review of biochemistry, 2022 - annualreviews.org
DNA replication in eukaryotic cells initiates from large numbers of sites called replication
origins. Initiation of replication from these origins must be tightly controlled to ensure the …

Origins of DNA replication in eukaryotes

Y Hu, B Stillman - Molecular cell, 2023 - cell.com
Errors occurring during DNA replication can result in inaccurate replication, incomplete
replication, or re-replication, resulting in genome instability that can lead to diseases such as …

The structural mechanism of dimeric DONSON in replicative helicase activation

MA Cvetkovic, P Passaretti, A Butryn… - Molecular Cell, 2023 - cell.com

DNA replication origin activation in space and time

M Fragkos, O Ganier, P Coulombe… - Nature reviews Molecular …, 2015 - nature.com
DNA replication begins with the assembly of pre-replication complexes (pre-RCs) at
